	Well... From my viewpoint, the quickest way is to load the list
correctly in the first place... Where does this list come from? If it's
a file of
		word		count
pairs, then

wordFreq2 = []
for ln in inputFile:
	(word, freq) = ln.strip().split()	#any line with more or less than
									#2 entries will fail
	wordFreq2.append(	(word, int(freq))	)

	Modify as needed if the file is
		word
		count
...
