Python | Remove spaces from string

Python Methods and Functions | Regular Expressions | String Variables

Examples :

  Input:  geek  Output:  geek  Input:  Hello World  Output:  HelloWorld

There are various approaches for removing whitespace from a string. The first — this is the Naive approach discussed in

B Output: 

 geek

Approach # 2 Using split () and join ()

First we use the split () function to return a list of words in a string using sep as the separator string ... We then use join () to join the iterable.

# Python3 code to remove spaces

def remove (string):

return string.replace ( "" , "")

 
# Driver program

string = `geek`

print (remove (string))

# Python3 code to remove spaces

def remove (string):

return "". join (string.split ())

  
# Driver program

string = `geek`

print (remove (string))

Output: 

 geek

Approach # 3: Using Python Regular Expressions

# Python3 code to remove spaces

import re

 

def remove (string):

pattern = re. compile ( r `s +` )

return re.sub (pattern, ``, string)

 
# Driver program

string = `geek`

print (remove (string))

Exit:

 geek

Approach # 4: Using translate()

# Python code to remove spaces

import string

 

def remove (string):

return string.translate ( None , `` )

 
# Driver program

string = `geek`

print (remove (string))

Exit:

 geek
