Python remove all whitespace in a string

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, you can use str.replace():

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

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

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