This is a Python script that simulates the Monty Hall problem.
With each round, two goats and one car are distributed randomly behind doors. The contestant always chooses door #1. The host will always choose door #2 if it's a goat, otherwise door #3. The contestant will then always choose door #2 or #3, depending on which door the host has chosen.
To play another round, hit the ENTER key. The script keeps a tally of how many goats vs. cars the contestant has won.
