What is the use of strip() in python

there are various way in which we can explain strip 

• When we use strip() then it removes all whitespaces from the beginning and the end of the string because there is nothing between the brackets.
• strip() is an inbuilt function in Python programming language that is used for removing beginning and ending character which is passed between the brackets.

Syntax:

string.strip([chars])

Example:-

string = """     geeks for geeks     """ 

  

# prints the string without stripping

print(string) 

  

# prints the string by removing leading and trailing whitespaces

print(string.strip())   

  

# prints by removing geeks

print(string.strip(' geeks'))







Output: geeks for geeks geeks for geeks for




by the above example I am sure you would have understood but then also let see another example.

Example:-

  

string1 = 'geeks for geeks'

# without striping.

print(string1)

  

# remove from original string at both its ends.

string2 = 'ekgs'

  

# Print string after striping string2 from str1 from beginning and end.

print(string1.strip(string2))

Output: geeks for geeks for

The best use of strip is in this program shown below:-

for i in range(int(input())): n = input().strip(); counts = n.count('4') + n.count('7') print(len(n)-counts)

In this program advantage of using strip is that when the input is given, the whitespaces in the beginning and end are removed.
