Perhaps you meant something more along the lines of this:

>>> def PrintWordCountFloat(words):
	number = 0
	for index, word in enumerate(words):
		print "%s %f" % (index, word)
		number = number + 1
	print "Total words: %d" %(number)
>>> PrintWordCountFloat(range(10))
0 0.000000
1 1.000000
2 2.000000
3 3.000000
4 4.000000
5 5.000000
6 6.000000
7 7.000000
8 8.000000
9 9.000000
Total words: 10

Or similar; I can't read your mind. Just know that enumerate(iterable)
yields (index, value) for each item in iterable.
