Hello,
I am writing a program in Python 3.3.0 which flips a coin 10 x times and
then counts the number of heads and tails. It obviously does something else
than I intended, and I am wondering what I did wrong:
import random
print ("""
This program flips a coin 10 times.
It then counts the number of heads and tails.
""")
flips = 0
heads = 0
tails = 0
while flips < 10:
flips = flips + 1
if random.randint(1,2) == 1:
heads = heads + 1
print("We've got " + str(heads) + " heads here."
if random.randint(1,2) == 2:
tails = tails + 1
print("We've got " + str(tails) + " tails here.")
This is what I get as output:
This program flips a coin 10 times.
It then counts the number of heads and tails.
We've got 1 tails here.
We've got 1 heads here.
We've got 2 tails here.
We've got 2 heads here.
We've got 3 tails here.
We've got 3 heads here.
We've got 4 tails here.
We've got 5 tails here.
We've got 4 heads here.
We've got 6 tails here.
We've got 7 tails here.
We've got 5 heads here.
Can anyone help?
Thank you so much!
All the best,
Rafael
