The heads and tails bit is a red herring.  Don't try and model it in
your code.  It does nothing more than signal a binary condition, and
provide a tag to hang the result on (at least in this context).

#!/usr/bin/python
import random

i=0
for flip in range(100):
  i += random.choice((0,1))

print "Heads: %d, Tails: %d" % (i, 100-i)
