You shouldn't start with writing code when you're not clear on how it
needs to work -- instead, start with pseudo code. In the same way, if
you can lift 200lbs you can start with 100lbs and then work your way up.
The pseudo code is a lot simpler to write than code:
# assume 0 is heads and 1 is tails
num_heads = num_tails = 0
- repeat 100 times:
get input from user
if input == quit: break loop
flip = random integer out of 0 and 1
if flip:
print tails
num_tails += 1
else:
print heads
num_heads += 1
print num_heads, num_tails
print Exiting...
To find out how to pick a random integer, see:
