Given a string, write a Python program to remove all spaces from it.
Examples:
Input : g e e k Output : geek Input : Hello World Output : HelloWorld
There are various approaches to remove whitespaces in a string. The first one is the Naive approach, which has been discussed in this article. But here we will discuss all the approaches which are specific to Python.
Approach#1 : Using replace()
Using replace() function, we replace all whitespace with no space(“”).
# Python3 code to remove whitespacedef remove(string): return string.replace(" ", "") # Driver Programstring = ' g e e k 'print(remove(string)) |

Approach #2 : Using split() and join()
First we use split() function to return a list of the words in the string, using sep as the delimiter string. Then, we use join() to concatenate the iterable.
# Python3 code to remove whitespacedef remove(string): return "".join(string.split()) # Driver Programstring = ' g e e k 'print(remove(string)) |

Approach #3 : Using Python regex
# Python3 code to remove whitespaceimport re def remove(string): pattern = re.compile(r'\s+') return re.sub(pattern, '', string) # Driver Programstring = ' g e e k 'print(remove(string)) |
geek
Approach #4 : Using translate()
# Python code to remove whitespaceimport string def remove(string): return string.translate(None, ' \n\t\r') # Driver Programstring = ' g e e k 'print(remove(string)) |
