Python String | strip()

The strip() method in-built function of Python is used to remove all the leading and trailing spaces from a string.

Syntax :string.strip([chars])

Parameter:

chars(optional): Character or a set of characters, that needs to be removed from the string.

Returns: A copy of the string with both leading and trailing characters stripped.

Using strip() method:

In case the character of the string to the left doesn’t match with the characters in the char parameter, the method stops removing the leading characters.
In case the character of the string to the right doesn’t match with the characters in the char parameter, the method stops removing the trailing characters.

Example #1:

Python3

# Python code to illustrate the working of strip()
string = '   Beginner for Beginner   '
 
# Leading spaces are removed
print(string.strip())
 
# Beginner is removed
print(string.strip('   Beginner'))
 
# Not removed since the spaces do not match
print(string.strip('Beginner'))

Output :

Beginner for Beginner
for
   Beginner for Beginner

Example #2:

Python3

# Python code to illustrate the working of strip()
string = '@@@@Beginner for Beginner@@@@@'
 
# Strip all '@' from beginning and ending
print(string.strip('@'))
 
string = 'www.w3wiki.net'
 
# '.grow' removes 'www' and 'org' and '.'
print(string.strip('.grow'))

Output:

Beginner for Beginner
w3wiki

Example #3:
The following code shows an application of strip() in python.

Python3

# Python code to check for identifiers
def Count(string):
 
    print("Length before strip()")
    print(len(string))
 
    # Using strip() to remove white spaces
    str = string.strip()
    print("Length after removing spaces")
    return str
 
 
# Driver Code
string = "  Beginner for Beginner   "
print(len(Count(string)))

Output:
