Remove all whitespace in a string in Python

Question

I want to eliminate all the whitespace from a string, on both ends, and in between words.

I have this Python code:

def my_handle(self): sentence = ' hello apple ' sentence.strip()

But that only eliminates the whitespace on both sides of the string. How do I remove all whitespace?

Answer 1

If you want to remove leading and ending spaces, use str.strip():

sentence = ' hello apple'
sentence.strip()
>>> 'hello apple'

If you want to remove all spaces, use str.replace():

sentence = ' hello apple'
sentence.replace(" ", "")
>>> 'helloapple'

If you want to remove duplicated spaces, use str.split():

sentence = ' hello apple'
" ".join(sentence.split())
>>> 'hello apple'

Hope this helps!!

You can also use regular expressions for this.

import re
pattern = re.compile(r'\s+')
sentence = re.sub(pattern, '', sentence)
