By applying a couple of other ideas that have been suggested you get
something shorter and arguably slightly clearer:
# Coin Flips
# The program flips a coin 100 times and then
# tells you the number of heads and tails
import random
print """
Welcome to 'Coin Flipper!'
I will flip a coin 100 times and then tell you
the number of heads and tails!
"""
headsCount = 0
for count in range(100):
if random.randrange(2): # returns 1/0 => true/False
headsCount += 1
print "The number of heads was", headsCount
print "The number of tails was", 100-headsCount
raw_input("\n\nPress the enter key to exit.")
And you could replace the whole for loop with a generator expression
if you really wanted to, but I suspect that is getting into advanced
territory for you at this stage...

Greetings,
As a thread starter, I thought I should write the rewritten code I got that
others helped me get to, since this thread is still going on.
# Coin Flips# The program flips a coin 100 times and then# tells you the number
of heads and tailsimport random
print "\a"print "\tWelcome to 'Coin Flipper!'"print "\nI will flip a coin 100
times and then tell you"print "the number of heads and tails!\n"
# set the coinheadsCount = 0tailsCount = 0count = 1
while count <= 100:coin = random.randrange(2)if coin == 0:
headsCount += 1else:tailsCount += 1count += 1
print "The number of heads was", headsCountprint "The number of tails was",
tailsCount
raw_input("\n\nPress the enter key to exit.")

Re: [Tutor] While Loops: Coin Flip Game :p:
Arrr thats better Nithya it works fine now. I had it working fine before it
was just coming up with that strange result of 73 and 100
when I copied the code into wing to check it out in order to understand it.
Wing picked up the spacing and I had already corrected
that Dave as I was simply looking at Nithya code.
