Thanks, I finally figured it out. Here it is #Coin Toss Game import random print"This game will simulate 100 coin tosses and then tell you the number of head's and tails"
tosses=0 heads=0 tails=0 while tosses<100: tosses<100 coin=random.randrange(2) tosses+=1 if coin==0: heads +=1 print "Heads" else: tails+=1 print "Tails" print"100 tosses have been simulated. Please wait for your results" print "\nOut of",tosses,",",heads,"were heads and",tails,"were tails." --- [EMAIL PROTECTED] wrote: > Send Tutor mailing list submissions to > tutor@python.org > > To subscribe or unsubscribe via the World Wide Web, > visit > http://mail.python.org/mailman/listinfo/tutor > or, via email, send a message with subject or body > 'help' to > [EMAIL PROTECTED] > > You can reach the person managing the list at > [EMAIL PROTECTED] > > When replying, please edit your Subject line so it > is more specific > than "Re: Contents of Tutor digest..." > > > Today's Topics: > > 1. coin toss program without using the for/range > loop (David) > 2.
