What Is Python Strip() with Examples
In this Python article, let's learn about What Is Python Strip() with Examples. What is Python strip()?: Python strip() is a built-in function included in the Python library. The strip() function removes leading and trailing spaces to return a copy of the original string. By default, the strip() method helps to remove whitespaces from the start and the end of the string.
Syntax of String strip()
Here is the syntax:
string.strip(chars)
strip() Parameters
Here is the strip() parameter:
The characters are a set of strings specifying the set of characters whose leading and trailing spaces have to be removed.
In case the optional characters parameter is not given, all leading and trailing whitespaces are removed from the string.
strip() Return Value
Here is the strip() Return Value:
It returns a copy of the string with both leading and trailing characters removed.
Example 1: strip() Method in Python
Let us see an example to remove the leading and trailing spaces from a given strip in Python using strip() method.
str1 = "Welcome to Great Learning!"
after_strip = str1.strip()Here’s what the output looks like:
Welcome to Great Learning
Example 2: strip() on Invalid Data Type
The strip() function in Python works only with strings. It will return an error if used for data types such as lists, tuples, etc.
Let us take an example where it is used for lists:
mylist = ["a", "b", "c", "d"]
print(mylist.strip()) Here’s what the output looks like:
Traceback (most recent call last):
File “teststrip.py”, line 2, in <module>
print(mylist.strip())
AttributeError: ‘list’ object has no attribute ‘strip’
The output shows an error.
Example 3: strip() Without character parameter
When used without a char parameter, here is how the strip() function works in Python:
str1 = "Welcome to Great Learning!"
after_strip = str1.strip()
print(after_strip)
str2 = "Welcome to Great Learning!"
after_strip1 = str2.strip()
print(after_strip1)Output
Here’s what the output looks like:
Welcome to Great Learning!
Example 4: strip() Passing character parameters
Here’s how to use the strip() function in this case:
str1 = "****Welcome to Great Learning!****"
after_strip = str1.strip("*")
print(after_strip)
str2 = "Welcome to Great Learning!"
after_strip1 = str2.strip("99!")
print(after_strip1)
str3 = "Welcome to Great Learning!"
after_strip3 = str3.strip("to")
print(after_strip3)Output:
Welcome to Great Learning!
Welcome to Great Learning
Welcome to Great Learning!
Why Python strip() function is used?
Strip() function in Python has a lot of useful advantages for developers. Here are the key reasons to use the strip() function –
- The strip() function helps in removing the characters, symbols, etc. at the start and end of the string to return the value of the original string.
- It also helps in removing the whitespaces from the start or the end of the given string.
- In case the character that needs to be removed is not specified and there are no whitespaces in the string then the string will return as it is.
- If the character parameters are specified but there are no whitespaces in the string then the string will be returned with the original whitespaces removed from it.
- If the character parameter is specified and the string contains a matching character at the beginning of the string, then those will be removed and the string is returned.
- If the character parameter is specified but the string does not contain a matching character either at the front or the end of the string, it will be returned as it is.
Frequently Asked Questions
What is Strip () in Python?
Strip() is a function in the Python library that helps to return the copy of the string after removing the leading and trailing characters, whitespaces, and symbols that have been passed to the strip() function. Simply put, the Python strip() function is responsible for the removal of characters from the left and the right side of the string. It is done so when a set of character parameters are specified as an argument to the strip() function. In case there is no argument, it will remove whitespaces by default.
What is a strip in Python example?
Here is an example of the strip() function in Python –
strinput = ” $$$$$ No. 1 Welcome to GREAT LEARNING!! No. 1 $$$ ”
# use strip() function to remove the set of characters
res = strinput.strip ( ‘ $No. 10 !’ ) # store result into res variable
print ( ” Given string is: “, strinput)
print ( ” After removing the set of characters: “, res)
str3 = ‘ 1 11 111 111 1111 Learn Python Tutorial 1111 111 11 1 ‘
str4 = str3. strip ( ‘1’ )

How do you type a strip in Python?
To remove any characters, whitespaces, or symbols, here is how to type strip() in Python –
strip( ‘characters’ )
Strip (‘chars’) is the parameter that can be optional. If the developer does not pass any argument to the strip() function, it simply removes the whitespaces from the beginning and the end of the string to return the original string.
If the developer specifies a set of characters as an argument to the strip() function, it removes those characters or symbols from the beginning and the end of the string to return the original string.
What is split and strip Python?
Python split() function breaks up a string to return the list of all strings. The programmer can specify the separator to the split() function which helps in splitting the string accordingly. If the programmer does not specify the separator, then the split() function will remove the whitespaces from the beginning and the end of the string by default.
This method is very useful in Python as it helps to break the string into substrings according to the instance of the separator is specified by the programmer. In the case where max split is specified, the returning value will contain the list containing the specified number of elements plus one.
Here’s the syntax of the split() function in Python:
string.split(separator, maxsplit)
A separator is optional here. If it is not provided, the string will split at the whitespaces.
Max split refers to the maximum number of splits. If this value if not provided, then there is no limit on the number of splits.
The output will return a list of strings
Let us check an example of the split() function in Python.
text= ‘Welcome to Great Learning’
# splits at space
print(text.split())
grocery = ‘Milk, Bread, Eggs’
# splits at ‘,’
print(grocery.split(‘, ‘))
# Splits at ‘:’
print(grocery.split(‘:’))
Output
Here’s what the output looks like:
[‘Welcome’, ‘to’, ‘Great’, ‘Learning’]
[‘Milk’, ‘Bread’, ‘Eggs’]
[‘Milk, Bread, Eggs’]
Python strip() function is primarily used to remove whitespaces from the start and the end of a string. For example,
Str1=” Hello, Learners”
print(str1.strip())
Output : Hello, Learners
In the above example, we used string with parameter characters. In the output, the strip() method returns the string by removing the specified character at the beginning and the end of that string.

How to Remove all Duplicate Files on your Drive via Python
Today you’re going to learn how to use Python programming in a way that can ultimately save a lot of space on your drive by removing all the duplicates.
Intro
In many situations you may find yourself having duplicates files on your disk and but when it comes to tracking and checking them manually it can tedious.
Heres a solution
Instead of tracking throughout your disk to see if there is a duplicate, you can automate the process using coding, by writing a program to recursively track through the disk and remove all the found duplicates and that’s what this article is about.
But How do we do it?
If we were to read the whole file and then compare it to the rest of the files recursively through the given directory it will take a very long time, then how do we do it?
The answer is hashing, with hashing can generate a given string of letters and numbers which act as the identity of a given file and if we find any other file with the same identity we gonna delete it.
There’s a variety of hashing algorithms out there such as
- md5
- sha1
- sha224, sha256, sha384 and sha512

How To Compare Tesla and Ford Company By Using Magic Methods in Python
Magic Methods are the special methods which gives us the ability to access built in syntactical features such as ‘<’, ‘>’, ‘==’, ‘+’ etc…
You must have worked with such methods without knowing them to be as magic methods. Magic methods can be identified with their names which start with __ and ends with __ like init, call, str etc. These methods are also called Dunder Methods, because of their name starting and ending with Double Underscore (Dunder).
Now there are a number of such special methods, which you might have come across too, in Python. We will just be taking an example of a few of them to understand how they work and how we can use them.
1. init
class AnyClass:
def __init__():
print("Init called on its own")
obj = AnyClass()
The first example is _init, _and as the name suggests, it is used for initializing objects. Init method is called on its own, ie. whenever an object is created for the class, the init method is called on its own.
The output of the above code will be given below. Note how we did not call the init method and it got invoked as we created an object for class AnyClass.
Init called on its own
2. add
Let’s move to some other example, add gives us the ability to access the built in syntax feature of the character +. Let’s see how,
class AnyClass:
def __init__(self, var):
self.some_var = var
def __add__(self, other_obj):
print("Calling the add method")
return self.some_var + other_obj.some_var
obj1 = AnyClass(5)
obj2 = AnyClass(6)
obj1 + obj2
