If you are like most developers, you have probably used the string strip() method at some point in your career. However, do you know what it is and how it works? Strip () is an inbuilt function in Python programming language that removes spaces of the characters, both leading and trailing, and returns a copy of the string.
In this article, we will provide a brief overview of the Python string strip() method and several example scenarios that will allow you to understand how it works. So read on to learn all you need to know about the string strip() method.

What is String Strip() Method ?
The string() strip method is used to remove characters from the end of a string. This can be useful if you want to empty out a certain area of a string without affecting the other characters. To use this method, you first need to create an object that contains the strings you want to work with. Next, call the strip() method on your object and specify where in the string you would like it to start removing characters.
Usage of Python String Strip() Method
- It helps remove symbols from the beginning and end of a string based on the symbols provided to be eliminated from the original string.
- The original string will be returned if the characters provided do not match.
- The whitespaces from the beginning and end of the original string will be removed if the characters to be deleted are not provided.
- The string will be returned as it is if there is no white space at the beginning or end.
1.Strip () with Character Parameters
Strip () with character parameters is an exciting feature of Python. It is perfect for removing unwanted characters from your text strings or extracting specific information from a long stream of data.
str1 = "##Welcome to Codeleaks##" after_strip = str1.strip("#") print(after_strip) str2 = "Welcome to Codeleaks" after_strip1 = str2.strip("leaks") print(after_strip1)
2.Strip() without Character Parameters
The strip method without character parameters will remove the string’s white spaces and return them.
str1 = "Welcome to Codeleaks" after_strip = str1.strip() print(after_strip) str2 = "Welcome to Codeleaks" after_strip1 = str2.strip() print(after_strip1)
3.Strip () For Invalid Datatype
Python’s strip() function only supports the data type ‘String.’ As a result, the strip method will only work on strings and not on any other data type. For example, if you attempt to use a data type other than string, The strip method fails with an error.
mylist = [1, 2, 3, 4] print(mylist.strip())
4.Python Strip() String Method | leading and trailing whitespaces
The strip() function can be used to remove leading and trailing whitespaces from a string. This is useful when you want to format text for output, or if you are removing excessive whitespace from a string in order to save space.
s = '\tWelcome to Codeleaks\n ' print(s) new_s = s.strip() print(new_s)
5.Python Strip() String Method | Leading and Trailing Characters
The strip() function removes leading and trailing characters from a string. Leading characters are the first character in a string while trailing characters are any additional characters that follow the last character in a string.
string = '@@Welcome to codeleaks' new_string = string.strip('@@') print(new_string)
What is the time complexity of strip Python?
M is the length of the actual string of characters to be stripped, and N * M is the time complexity.
What is the difference between Split and strip in Python?
There is no differentiation between the two. By default, split() removes whitespace at the ends of the input. Some people prefer to use strip() initially because they believe it is more evident or that they are unaware of the split().
In this article, we discussed the Python strip() String method in detail and gave examples to clarify its usage. We saw how you could use strip() method to remove characters from the end of a string. The method is relatively simple but powerful as it does not affect the rest of the strings. I hope this article helped you to understand Python strip() string method. Happy coding.
