Split with no arguments splits on whitespace, and multiple spaces
count as but a single separator.  So split+join = collapsed
whitespace.

>>> test = "a  b c d   efdd  slkj   sdfdsfl"
>>> " ".join(test.split())
'a b c d efdd slkj sdfdsfl'

Or use something other than " " to join with, such as ",".
>>> ",".join(test.split())
'a,b,c,d,efdd,slkj,sdfdsfl'
