[word for word in words.split()] ?

No need for a list comprehensions here. How about this... 
def reverseWords(words):
    return ' '.join(words.split()[::-1])

    It is sometimes hard to not use ::-1 once learnt, but you can use reversed which makes it clearer: 
    >>> def reverseWords(word):
... 	return " ".join( reversed(word.split()) )
... 
>>> reverseWords("  one   two three four    ")
'four three two one'
