remove unwanted space in between a string [duplicate]

Question

I wanna know how to remove unwanted space in between a string. For example:

>>> a = "Hello    world" 

and i want to print it removing the extra middle spaces.

Hello world

Answer 1

This will work:

" ".join(a.split())

Without any arguments, a.split() will automatically split on whitespace and discard duplicates, the " ".join() joins the resulting list into one string.

Answer 2

Regular expressions also work

>>> import re
>>> re.sub(r'\s+', ' ', 'Hello     World')
'Hello World'
