regex - how to get this Simple regular expression to work in python? -

i'm regex newbie

i'm trying remove occurrences of \n & \s\s (double white space) , , (comma)

this program

import re;  text = "this cool thing do,         \n blah"  re.sub('(,|\\n|\s\s)','',text)  print text; 

but doesn't replace anything. should fix?

re.sub not modify input. returns new string. if want replace original string, assign result original variable:

text = re.sub('(,|\\n|\s\s)','',text)
