When I run this code (I'm also a noob) I get this result:-
>>> [evaluate lines 1-22 from untitled-1.py]
The number of heads was 73
The number of tails was 100
Press the enter key to exit.
# Surely, if flipping a single coin 100 times your total number of heads and
tails should add up to 100
# not 173 or am I missing the point?
