As far as I can see, you want to have the words, that all three lists
have in common, right?

s0 = "this is an example of a thing i would like to have".split()
s1 = "another example of something else i would like to have".split()
s2 = 'and this is another " example " but of something ; now i would
still like to have'.split()

def findCommons(s0, s1, s2):
	res = []
	for word in s0:
		if word in s1 and word in s2:
			res.append(word)
	return res

 >>>print findCommons(s0,s1,s2)
 ['example', 'of', 'i', 'would', 'like', 'to', 'have']
