Greetings,
I'm a Python beginner and working my way through Michael Dawson's
Python Programming for the Absolute Beginner. I'm stuck in a
particular challenge that asks me to write a program that "flips a
coin 100 times and then tells you the number of heads and tails." I've
been trying to work on this challenge for a while now and can't get it
to work (either it has 100 heads or 100 tails). I've been reworking
this code many times and currently what I have does not do anything at
all at IDLE. Please take a look at my code below:
import random
# set the coin
coin = random.randrange(2)
headsCount = 0
tailsCount = 0
count = 0
# the loop
while count <= 100:
coin
if coin == 0:
headsCount += 1
if coin == 1:
tailsCount += 1
count += 1
print "The number of heads was", heads
print "The number of tails was", tails
raw_input("\n\nPress the enter key to exit.")
Thanks,
S. Dawn Samson
You try to print two variables, "heads" and "tails" which don't exist.
The other replies covered the other main problems.
