Please tell me you're making fun of the poor newbie and didn't mean to 
seriously suggest using a regex merely to split on whitespace?

>>> import timeit
>>> timeit.Timer("s.split()", "s = 'one   two  three     four'").repeat()
[1.4074358940124512, 1.3505148887634277, 1.3469438552856445]
>>> timeit.Timer("re.split('\s+', s)", "import re;s = 'one   two  
three     four'").repeat()
[7.9205508232116699, 7.8833441734313965, 7.9301259517669678]
