Hi there,

This is the Code. Please check it.It is working fine.

import random
headsCount = 0
tailsCount = 0
count = 1

while count = 100:
   coin = random.randrange(2)
   if coin == 0:
 headsCount += 1
   else:
 tailsCount += 1
   count += 1

print The number of heads was, headsCount
print The number of tails was, tailsCount

raw_input(\n\nPress the enter key to exit.)

  No, you're missing an indentation.  If you check the code you're running,
 I think you'll find that you didn't unindent the line incrementing count.

 Of course, it's less error prone to simply use
 for count in xrange(100):

 instead of while count  100:

 and you wouldn't need to increment count.

 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.

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.

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...

HTH,

Hi Tom,

Your code is almost correct. Little mistake is there.The random number
generate should be in while loop.

 import random

 # set the coin

 headsCount = 0
 tailsCount = 0
 count = 0

 # the loop
 while count  100:   #If
you declare count = 0. The while loop condition should be  less than
100.Else you will get 101 counts.
 *coin = random.randrange(2)*
 if coin == 0:
 headsCount += 1
else:   #Becase We
already declared randrange(2).So the coin value is 0 or 1.So we can use else
condition.
 tailsCount += 1
 count += 1


 print The number of heads was, headsCount
 print The number of tails was, tailsCount

 raw_input(\n\nPress the enter key to exit.)

 From one beginner to another - it looks to me like you set the value of
 coin once then checked it 100 times.  If you want to reset the value of
 coin maybe it (i.e. setting the value of coin, not just calling
 the value of coin) should be in the loop too?
