How to strip whitespace from before but not after punctuation in python

relative python newbie here. I have a text string output from a program I
can't modify. For discussion lets say:
text = "This text . Is to test . How it works ! Will it! Or won't it ? Hmm ?"
I want to remove the space before the punctuation, but not remove the
second space. I've been trying to do it with regex, and I know that I can
match the instances I want using match='\s[\?.!\"]\s' as my search term.
x=re.search('\s[\?\.\!\"]\s',text)
Is there a way with a re.sub to replace the search term with the leading
whitespace removed? Any ideas on how to proceed?
