Python string | strip() - GeeksforGeeks

strip() is an inbuilt function in Python programming language that returns a copy of the string with both leading and trailing characters removed (based on the string argument passed).
Syntax:

string.strip([chars])
Parameter: 
There is only one optional parameter in it:
1)chars - a string specifying 
the set of characters to be removed. 

If the optional chars parameter is not given, all leading 
and trailing whitespaces are removed from the string.
Return Value:
Returns a copy of the string with both leading and trailing characters removed.

# Python3 program to demonstrate the use of 
# strip() method   
  
string = " geeks for geeks " 
  
# prints the string without stripping 
print(string)  
  
# prints the string by removing leading and trailing whitespaces 
print(string.strip())    
  
# prints the string by removing geeks 
print(string.strip(' geeks')) 

Output:

 geeks for geeks 
geeks for geeks
for

Errors:
There is a runtime error when we try to strip anything except a string. The system gives a output showing

# Python3 program to demonstrate the use of 
# strip() method error 
  
string = " geeks for geeks "
list =[1, 2, 3]  
  
# prints the error message 
print(list.strip())  

Output:

Traceback (most recent call last):
  File "/home/1bdead5a6ad1dbb0db1c6a2663874e4c.py", line 8, in 
    print(list.strip()) 
AttributeError: type object 'list' has no attribute 'strip'

Practical application:
Given a string remove occurrence of word “The” from the beginning and the end.

# Python3 program to demonstrate the practical application 
# strip()  
  
  
string = " the King has the largest army in the entire world the" 
  
# prints the string after removing the from beginning and end 
print(string.strip(" the")) 

Output:

King has the largest army in the entire world
