Your programm gives an error. You are trying to concatenate strings with  integers.

http://docs.python.org/lib/typesseq-strings.html

import random
heads = 0
tails = 0
flips = 0
while flips < 99:
        coin = random.randrange(0, 2)
        if coin == 0:
            heads = heads + 1
        else:
            tails = tails + 1
        flips = flips + 1
if flips >= 99:
        print "Heads: %s" % heads	## string formatting
        print "Tails: %s"  %tails	## string formatting
        print "Total: %s flips" % flips	## string formatting
raw_input("Press the enter key to exit.")
