>> s[:s.find("/")] 'abcde' So, word[-1:] basically means ‘from the second last character to the end of the string. >>> 'foo bar foo baz foo qux'.replace('foo', 'grault') 'grault bar grault baz grault qux'. Note that, by default, replace() will replace every occurrence of the search sub-string with the new sub-string. In practice, it's easy. If you like GeeksforGeeks and would like to contribute, you can also write an article using contribute.geeksforgeeks.org or mail your article to contribute@geeksforgeeks.org. Slicing Strings. As we have not provided the count parameter in replace() function. Let's look at what's happening here. This N can be 1 or 4 etc. If the length of the string is less than 3 then return the original string. If, as in the cases we've met so far, the parameter is omitted, it defaults to 1, so that every character in the specified segment is retrieved. The first character has the position 0, the second has position 1, and so on. Check if both halves of the string have same set of characters in Python; Python | Split string into list of characters; Python - Split Numeric String into K digit integers; Python | Split a list into sublists of given lengths; Split a String into columns using regex in pandas DataFrame; Split a string in equal parts (grouper in Python) You can return a range of characters by using the slice syntax. Tip: Use a negative number to select from the end of the string. Yes, in goddamn PHP! By the way, we can choose not to specify a delimiter explicitly, in which case it defaults to a white-space character (space, '\t', '\n', '\r', '\f') or sequence of such characters. Each character in this string has a sequence number, and it starts with 0 i.e. In this example, we are using Negative values as the endpoint. I have been developing on the Web for more than five years now - in PHP. If left blank, deletes whitespace at the end. The strip() to Trim a String in Python. For example, an index of -1 refers to the right-most character of the string. Generate two output strings depending upon occurrence of character in input string in Python; manjeet_04. A character is anything you can type on the keyboard in one keystroke, like a letter, a number, or a backslash. Specify the start index and the end index, separated by a colon, to return a part of the string. Strengthen your foundations with the Python Programming Foundation Course and learn the basics. In Python, when you need to get a sequence of characters from a string (i.e., a substring ), you get a slice of the string using the following syntax: substring = original_string [first_pos:last_pos] When slicing in Python, note that: Python lstrip() function removes only leading whitespace chars. Python rstrip () function removes only trailing whitespace chars. Typically it's more useful to access the individual characters of a string by using Python's array-like indexing syntax. Python strings are immutable, which is just a fancy way of saying that once they've been created, you can't change them. To preserve our new string, we need to assign it to a variable. Use the start and end parameters to specify the part of the string you want to extract. Now, lets replace all the occurrences of ‘s’ with ‘X’ i.e. I know, it can make your head ache thinking about it, but Python knows what it's doing. By this, you can allow users to use this function as any built-in function. So, it will replace all the occurrences of ‘s’ with ‘X’. As with the split() method, there is a variant of partition(), rpartition(), that begins its search for delimiters from the other end of the target string. #python; #string; #substring; How to check if a character / substring is in a string or not # Let me start with a little history about myself. Check out this Author's contributed articles. Now, back to our Don Quijote. Before that, what if you want to extract a chunk of more than one character, with known position and size? He relaxes by making things out of rope, including "monkey's fist" keyrings that are used in the Tower of London. For example, we have a string variable sample_str that contains a string i.e. Mystring = 'Learn splitting string'. In other words, we can tell Python to look for a certain substring within our target string, and split the target string up around that sub-string. white spaces and leading and trailing spaces from Python string. s.replace (, ) returns a copy of s with all occurrences of substring replaced by : >>>. In Python, to remove a character from a string, you can use the Python string .replace () method. An example makes this clearer. You can trim a string in Python using three built-in functions. Using this syntax, you can omit either or both of the indices. You can specify a negative stride too. More usefully, we can garner up the returned list directly into appropriate variables. And so on, until the ending index is reached or exceeded. Either of the first two would work pretty well. Finally, the replace() method is not limited to acting on single characters. Python substring functions. Let’s see how to do that, In this article, we will discuss how to fetch the last N characters of a string in python. Next: Write a Python function to reverse a string if it's length is a multiple of 4. An empty string is a string that has 0 characters. But that's not the way it works. # Return a character, then move forward 2 positions, etc. Python string slicing accepts the negative values as well to get the substring. In Python, when you need to get a sequence of characters from a string (i.e., a substring ), you get a slice of the string using the following syntax: substring = original_string [first_pos:last_pos] When slicing in Python, note that: That's fairly easy and intuitive. suffix − This could be a string or could also be a tuple of suffixes to look for.. start − The slice begins from here. A string is composed of characters each of which has a numeric index starting from 0. Examples: Input : geeks Output : ['g', 'e', 'e', 'k', 's'] Input : Word Output : ['W', 'o', 'r', 'd'] Code #1 : Using For loop This approach uses for loop to convert each character into a list. So the output of this code is –. You can return a range of characters by using the slice syntax. Here, as with all sequences, it's important to remember that indexing is zero-based; that is, the first item in the sequence is number 0. As you might expect, this indicates that you want Python to go backwards when retrieving characters. So that's the square-bracket syntax, which allows you to retrieve chunks of characters if you know the exact position of your required chunk in the string. The split() method will accept a second parameter that specifies the maximum number of splits to perform. For example, we have a string variable sample_str that contains a string i.e. Attention geek! You might have thought that you were going to get the character at position 8 too. Again, our string hasn't been changed at all. Overview A string is a list of characters in order. Strings can have spaces: "hello world". Python offers many ways to substring a string. Python strip() function removes specific whitespace chars for example: myString.strip(‘\n’) or myString.lstrip(‘\n\r’) or myString.rstrip(‘\n\t’) and so on. What has happened is that Python simply returned a new string according to the instructions we gave, then immediately discarded it, leaving our original string unaltered. Strings are Arrays. In the below python program, we will use join() to remove special characters from a given string. splitted_string = Mystring.split() print('Splitted String is : ', splitted_string) This code will split string at whitespace. Python strings are immutable Python recognize as strings … Therefore member functions like replace() returns a new string. A similar string method is partition(). sample_str = "Hello World !!" Specify the start index and the end index, separated by a colon, to return a part of the string. Negative values mean, it counts from rightmost character to the left. And if the number of variables we supply doesn't match with the number of characters in the string, Python will give us an error. The slice() method extracts parts of a string and returns the extracted parts in a new string. Just as before, you can use negative numbers as indices, in which case the counting starts at the end of the string (with an index of -1) instead of at the beginning. Think of it … splitted_string = Mystring.split() print('Splitted String is : ', splitted_string) This code will split string at whitespace. The last is overkill here and I wouldn't use it, but regexs are often appropriate for doing search & replace operations. For references on the string methods used, see the following: When not programming in Python, Doug fills in the time by writing articles, editing books, teaching English as a foreign language and doing translations. Suppose we have a string i.e. Examples: Input : geeks Output : ['g', 'e', 'e', 'k', 's'] Input : Word Output : ['W', 'o', 'r', 'd'] Code #1 : Using For loop This approach uses for loop to convert each character into a list. To split, you need to specify the character you want to split into: str.split(" ") The trim function is called strip in python: str.strip() Also, you can do str[:7] to get just "vendor x" in your strings. String slicing can accept a third parameter in addition to two index numbers. The final variation on the square-bracket syntax is to add a third parameter, which specifies the 'stride', or how many characters you want to move forward after each character is retrieved from the original string. In this case, we might reasonably gather up the separate parts into variables for further manipulation. Don't worry – you'll get used to it. So the output of this code is –. To begin with, your interview preparations Enhance your Data Structures concepts with the Python DS Course. Thus, the string “python” has 6 characters with ‘p’ at index 0, ‘y’ at index 1 and so on. This also splits up a string based on content, the differences being that the result is a tuple, and it preserves the delimiter, along with the two parts of the target string on either side of it. The string method that allows us to do this is replace(). Python Strings Slicing Strings Modify Strings Concatenate Strings Format Strings Escape Characters String Methods String Exercises. Incidentally, a benefit of this mechanism is that you can quickly tell how many characters you are going to end up with simply by subtracting the first index from the second. AskPython is part of JournalDev IT Services Private Limited, 2 Easy Ways to Extract Digits from a Python String, Strings in Python – The Complete Reference, Understanding Python String expandtabs() Function, 4 Techniques to Create Python Multiline Strings, Technique 1: The strip() to Trim a String in Python. filter_none. Let us look at an example to understand it better. The first index, if omitted, defaults to 0, so that your chunk starts from the beginning of the original string; the second defaults to the highest position in the string, so that your chunk ends at the end of the original string. ... Python String split() Method String Methods. The first depends on the search string appearing though. As you can see, since we're going backwards, it makes sense for the starting index to be higher than the ending index (otherwise nothing would be returned). After executing the program, the output will be: Original String : Hel;lo *w:o!r;ld * de*ar ! The first depends on the search string appearing though. filter_none. But what if you want to retrieve a chunk based on the contents of the string, which we may not know in advance? Description. In Python, to remove a character from a string, you can use the Python string .replace () method. This function does the actual work of formatting. Instead of slicing the object every time, you can create a function that slices the string and returns a substring. Python strings are sequences of individual characters, and share their basic methods of access with those other Python sequences – lists and tuples. However, Python does not have a character data type, a single character is simply a string with a length of 1. I have been developing on the Web for more than five years now - in PHP. But we can get around this by creating a new string that's more to our liking, based on the old string. s.replace (, ) returns a copy of s with all occurrences of substring replaced by : >>>. Python Split String By Character. Given a string, write a Python program to split the characters of the given string into a list. It means, print (string [2 : -13]) returns substring from 2 to end … As it can be seen in the output image, the Name was sliced and 2 characters were skipped during slicing. If the indexing mechanism were inclusive, the character at position n would appear twice. #python; #string; #substring; How to check if a character / substring is in a string or not # Let me start with a little history about myself. Output: In the ab… Python string is a sequence of characters and each character in it has an index number associated with it. Python provides string methods that allows us to chop a string up according to delimiters that we can specify. We'll look at how in a minute. Characters at even position will be those whose index is divisible by 2. Again, Python will start at 0. Omitting both indices isn't likely to be of much practical use; as you might guess, it simply returns the whole of the original string. It is often called ‘slicing’. Code faster with the Kite plugin for your code editor, featuring Line-of-Code Completions and cloudless processing. Output : The original string : GeeksforGeeks is best for geeks The split string : best String after the substring occurrence : for geeks. And here, although it may seem that we've changed the original string, in actual fact we've just discarded it and stored a new string in its place. For example, say we have a string “Python is great”, and we want a list which would contain only the given names previously separated by spaces, we can get the required list just by splitting the string into parts on the basis of the position of space. And create a new string in python. So far, we have omitted the stride parameter, and Python defaults to the stride of 1, so that every character between two index numbers is retrieved. print("The split string : " + str(spl_word)) res = test_string.partition (spl_word) [2] print("String after the substring occurrence : " + res) chevron_right. After Remove special char : Hello world dear 2: Remove special characters from string in python using join() + generator. Yes, in goddamn PHP! The third parameter specifies the stride, which refers to how many characters to move forward after the first character is retrieved from the string. Previous: Write a Python function to get a string made of its first three characters of a specified string. Python string.strip() function basically removes all the leading … When we need to convert a string to list in Python containing the constituent strings of the parent string(previously separated by some separator like‘,’or space), we use this method to accomplish the task. Remember that these methods have no effect on the string on which you invoke them; they simply return a new string. Good luck Unfortunately, it's not often that we have the luxury of knowing in advance how many variables we are going to need in order to store every character in the string. Skipping character while splitting Python strings The final variation on the square-bracket syntax is to add a third parameter, which specifies the 'stride', or how many characters you want to move forward after each character is retrieved from the original string. The first retrieved character always corresponds to the index before the colon; but thereafter, the pointer moves forward however many characters you specify as your stride, and retrieves the character at that position. It does that by returning a list of the resulting sub-strings (minus the delimiters). Square brackets can be used to access elements of the string. Example. If left blank, deletes whitespace..rstrip() #strips everything out from the end up to and including the character or set of characters you give. In the output, you can see that the string is broken up into a list of strings. We can control this extravagance by adding an extra parameter specifying the maximum number of times that the search substring should be replaced. Contents of otherStr is as follows, As strings are immutable in Python, so we can not change its content. Leaving our Spanish hero to his windmills for a moment, let's imagine that we have a string containing a clock time in hours, minutes and seconds, delimited by colons. But of course, instead of introducing a new variable, we can just reuse the existing one. Unlike split(), partition() always does only one splitting operation, no matter how many times the delimiter appears in the target string. Well, there is a variant method called rsplit(), which does just that. We can replace a whole chunk of the target string with some specified value. So, by cutting off the characters before the character I want to remove and the characters after and sandwiching them together, I can remove the unwanted character. print("The split string : " + str(spl_word)) res = test_string.partition (spl_word) [2] print("String after the substring occurrence : " + res) chevron_right. If you want to modify a string, you have to create it as a totally new string. Get the last character of the string; string = "freeCodeCamp" print(string[-1]) Output: > p. Get the last 5 characters of a string; string = "freeCodeCamp" print(string[-5:]) Output: > eCamp. We extend the square-bracket syntax a little, so that we can specify not only the starting position of the piece we want, but also where it ends. If you want to start counting from the end of the string, instead of the beginning, use a negative index. Python string method endswith() returns True if the string ends with the specified suffix, otherwise return False optionally restricting the matching with the given indices start and end.. Syntax str.endswith(suffix[, start[, end]]) Parameters. Split a string into a list where each word is a list item: txt = "welcome to the jungle" Just as before, we're specifying that we want to start at position 4 (zero-based) in the string. Like the list data type that has items that correspond to an index number, each of a string’s characters also correspond to an index number, starting with the index vformat (format_string, args, kwargs) ¶. Here, the string is split on the first colon, and the remainder is left untouched. We might only want to split the target string once, no matter how many times the delimiter occurs. Let’s sum it up these functions. Earlier on, when we tried to anglicise his name by changing the 'j' to an 'x' by assigning the 'x' directly to s[7], we found that we couldn't do it, because you can't change existing Python strings. It follows this template: string[start: end: step] Where, start: The starting index of the substring.The character at this index is included in the substring. In python, a String is a sequence of characters, and each character in it has an index number associated with it. Python lstrip () function removes only leading whitespace chars. Mystring = 'Learn splitting string'. Either of the first two would work pretty well. Kite is a free autocomplete for Python developers. Python strip () function removes specific whitespace chars for example: myString.strip (‘\n’) or myString.lstrip (‘\n\r’) or myString.rstrip (‘\n\t’) and so on. >>> 'foo bar foo baz foo qux'.replace('foo', 'grault') 'grault bar grault baz grault qux'. Get a substring which contains all characters except the last 4 characters and the 1st character; string = "freeCodeCamp" print(string[1:-4]) Output: > reeCode More examples Python rstrip() function removes only trailing whitespace chars. If it helps, think of the second index (the one after the colon) as specifying the first character that you don't want. white spaces and leading and trailing spaces from Python string .

python cut string after character

December 29th, 2020 by

It is exposed as a separate function for cases where you want to pass in a predefined dictionary of arguments, rather than unpacking and repacking the dictionary as individual arguments using the *args and **kwargs syntax. Given a string, write a Python program to split the characters of the given string into a list. # Returns from pos 4 to the end of the string, # 1 is the default value anyway, so same result. Slicing Strings. The simplest way of extracting single characters from strings (and individual members from any sequence) is to unpack them into corresponding variables. Output : The original string : GeeksforGeeks is best for geeks The split string : best String after the substring occurrence : for geeks. For that reason, if you specify a negative stride, but omit either the first or second index, Python defaults the missing value to whatever makes sense in the circumstances: the start index to the end of the string, and the end index to the beginning of the string. And if we want Python to start looking for delimiters from the other end of the string? # End index defaults to the beginning of the string, # Beginning index defaults to the end of the string, Python’s string.replace() Method – Replacing Python Strings, How to Get a Sub-string From a String in Python – Slicing Strings, Encoding and Decoding Strings (in Python 3.x), Python Unicode: Encode and Decode Strings (in Python 2.x), What is python used for: Beginner’s Guide to python, Singly Linked List: How To Insert and Print Node, Singly Linked List: How To Find and Remove a Node, List in Python: How To Implement in Place Reversal. If you're still struggling to get your head around the fact that, for example, s[0:8] returns everything up to, but not including, the character at position 8, it may help if you roll this around in your head a bit: for any value of index, n, that you choose, the value of s[:n] + s[n:] will always be the same as the original target string. Index of last character will always be equal to the length of string – 1. Python Split String By Character. But what if we want to replace only first few occurrences instead of all? In the output, you can see that the string is broken up into a list of strings. The last is overkill here and I wouldn't use it, but regexs are often appropriate for doing search & replace operations. Attempting to do so triggers an error. But now, instead of contenting ourselves with a single character from the string, we're saying that we want more characters, up to but not including the character at position 8. Like many other popular programming languages, strings in Python are arrays of bytes representing unicode characters. Otherwise, s.find will return -1 and then s[:-1] will lop off the last character: >>> s = "abcdef" >>> s[:s.find("/")] 'abcde' So, word[-1:] basically means ‘from the second last character to the end of the string. >>> 'foo bar foo baz foo qux'.replace('foo', 'grault') 'grault bar grault baz grault qux'. Note that, by default, replace() will replace every occurrence of the search sub-string with the new sub-string. In practice, it's easy. If you like GeeksforGeeks and would like to contribute, you can also write an article using contribute.geeksforgeeks.org or mail your article to contribute@geeksforgeeks.org. Slicing Strings. As we have not provided the count parameter in replace() function. Let's look at what's happening here. This N can be 1 or 4 etc. If the length of the string is less than 3 then return the original string. If, as in the cases we've met so far, the parameter is omitted, it defaults to 1, so that every character in the specified segment is retrieved. The first character has the position 0, the second has position 1, and so on. Check if both halves of the string have same set of characters in Python; Python | Split string into list of characters; Python - Split Numeric String into K digit integers; Python | Split a list into sublists of given lengths; Split a String into columns using regex in pandas DataFrame; Split a string in equal parts (grouper in Python) You can return a range of characters by using the slice syntax. Tip: Use a negative number to select from the end of the string. Yes, in goddamn PHP! By the way, we can choose not to specify a delimiter explicitly, in which case it defaults to a white-space character (space, '\t', '\n', '\r', '\f') or sequence of such characters. Each character in this string has a sequence number, and it starts with 0 i.e. In this example, we are using Negative values as the endpoint. I have been developing on the Web for more than five years now - in PHP. If left blank, deletes whitespace at the end. The strip() to Trim a String in Python. For example, an index of -1 refers to the right-most character of the string. Generate two output strings depending upon occurrence of character in input string in Python; manjeet_04. A character is anything you can type on the keyboard in one keystroke, like a letter, a number, or a backslash.

As you can see, since we're going backwards, it makes sense for the starting index to be higher than the ending index (otherwise nothing would be returned). After executing the program, the output will be: Original String : Hel;lo *w:o!r;ld * de*ar ! The first depends on the search string appearing though. filter_none. But what if you want to retrieve a chunk based on the contents of the string, which we may not know in advance? Description. In Python, to remove a character from a string, you can use the Python string .replace () method. This function does the actual work of formatting. Instead of slicing the object every time, you can create a function that slices the string and returns a substring. Python strings are sequences of individual characters, and share their basic methods of access with those other Python sequences – lists and tuples. However, Python does not have a character data type, a single character is simply a string with a length of 1. I have been developing on the Web for more than five years now - in PHP. But we can get around this by creating a new string that's more to our liking, based on the old string. s.replace (, ) returns a copy of s with all occurrences of substring replaced by : >>>. Python Split String By Character. Given a string, write a Python program to split the characters of the given string into a list. It means, print (string [2 : -13]) returns substring from 2 to end … As it can be seen in the output image, the Name was sliced and 2 characters were skipped during slicing. If the indexing mechanism were inclusive, the character at position n would appear twice. #python; #string; #substring; How to check if a character / substring is in a string or not # Let me start with a little history about myself. Output: In the ab… Python string is a sequence of characters and each character in it has an index number associated with it. Python provides string methods that allows us to chop a string up according to delimiters that we can specify. We'll look at how in a minute. Characters at even position will be those whose index is divisible by 2. Again, Python will start at 0. Omitting both indices isn't likely to be of much practical use; as you might guess, it simply returns the whole of the original string. It is often called ‘slicing’. Code faster with the Kite plugin for your code editor, featuring Line-of-Code Completions and cloudless processing. Output : The original string : GeeksforGeeks is best for geeks The split string : best String after the substring occurrence : for geeks. And here, although it may seem that we've changed the original string, in actual fact we've just discarded it and stored a new string in its place. For example, say we have a string “Python is great”, and we want a list which would contain only the given names previously separated by spaces, we can get the required list just by splitting the string into parts on the basis of the position of space. And create a new string in python. So far, we have omitted the stride parameter, and Python defaults to the stride of 1, so that every character between two index numbers is retrieved. print("The split string : " + str(spl_word)) res = test_string.partition (spl_word) [2] print("String after the substring occurrence : " + res) chevron_right. After Remove special char : Hello world dear 2: Remove special characters from string in python using join() + generator. Yes, in goddamn PHP! The third parameter specifies the stride, which refers to how many characters to move forward after the first character is retrieved from the string. Previous: Write a Python function to get a string made of its first three characters of a specified string. Python string.strip() function basically removes all the leading … When we need to convert a string to list in Python containing the constituent strings of the parent string(previously separated by some separator like‘,’or space), we use this method to accomplish the task. Remember that these methods have no effect on the string on which you invoke them; they simply return a new string. Good luck Unfortunately, it's not often that we have the luxury of knowing in advance how many variables we are going to need in order to store every character in the string. Skipping character while splitting Python strings The final variation on the square-bracket syntax is to add a third parameter, which specifies the 'stride', or how many characters you want to move forward after each character is retrieved from the original string. The first retrieved character always corresponds to the index before the colon; but thereafter, the pointer moves forward however many characters you specify as your stride, and retrieves the character at that position. It does that by returning a list of the resulting sub-strings (minus the delimiters). Square brackets can be used to access elements of the string. Example. If left blank, deletes whitespace..rstrip() #strips everything out from the end up to and including the character or set of characters you give. In the output, you can see that the string is broken up into a list of strings. We can control this extravagance by adding an extra parameter specifying the maximum number of times that the search substring should be replaced. Contents of otherStr is as follows, As strings are immutable in Python, so we can not change its content. Leaving our Spanish hero to his windmills for a moment, let's imagine that we have a string containing a clock time in hours, minutes and seconds, delimited by colons. But of course, instead of introducing a new variable, we can just reuse the existing one. Unlike split(), partition() always does only one splitting operation, no matter how many times the delimiter appears in the target string. Well, there is a variant method called rsplit(), which does just that. We can replace a whole chunk of the target string with some specified value. So, by cutting off the characters before the character I want to remove and the characters after and sandwiching them together, I can remove the unwanted character. print("The split string : " + str(spl_word)) res = test_string.partition (spl_word) [2] print("String after the substring occurrence : " + res) chevron_right. If you want to modify a string, you have to create it as a totally new string. Get the last character of the string; string = "freeCodeCamp" print(string[-1]) Output: > p. Get the last 5 characters of a string; string = "freeCodeCamp" print(string[-5:]) Output: > eCamp. We extend the square-bracket syntax a little, so that we can specify not only the starting position of the piece we want, but also where it ends. If you want to start counting from the end of the string, instead of the beginning, use a negative index. Python string method endswith() returns True if the string ends with the specified suffix, otherwise return False optionally restricting the matching with the given indices start and end.. Syntax str.endswith(suffix[, start[, end]]) Parameters. Split a string into a list where each word is a list item: txt = "welcome to the jungle" Just as before, we're specifying that we want to start at position 4 (zero-based) in the string. Like the list data type that has items that correspond to an index number, each of a string’s characters also correspond to an index number, starting with the index vformat (format_string, args, kwargs) ¶. Here, the string is split on the first colon, and the remainder is left untouched. We might only want to split the target string once, no matter how many times the delimiter occurs. Let’s sum it up these functions. Earlier on, when we tried to anglicise his name by changing the 'j' to an 'x' by assigning the 'x' directly to s[7], we found that we couldn't do it, because you can't change existing Python strings. It follows this template: string[start: end: step] Where, start: The starting index of the substring.The character at this index is included in the substring. In python, a String is a sequence of characters, and each character in it has an index number associated with it. Python lstrip () function removes only leading whitespace chars. Mystring = 'Learn splitting string'. Either of the first two would work pretty well. Kite is a free autocomplete for Python developers. Python strip () function removes specific whitespace chars for example: myString.strip (‘\n’) or myString.lstrip (‘\n\r’) or myString.rstrip (‘\n\t’) and so on. >>> 'foo bar foo baz foo qux'.replace('foo', 'grault') 'grault bar grault baz grault qux'. Get a substring which contains all characters except the last 4 characters and the 1st character; string = "freeCodeCamp" print(string[1:-4]) Output: > reeCode More examples Python rstrip() function removes only trailing whitespace chars. If it helps, think of the second index (the one after the colon) as specifying the first character that you don't want. white spaces and leading and trailing spaces from Python string .
