This is a foundation game that illustrates several techniques:
- Game flow is controlled in the main() method and this is called using the best practice using name.
- An infinite loop in the main method that prompts to "Play Again."
- Global scores that are referenced in the function by using the "global" keyword.
- User input validation and looping when an invalid choice is entered. When a valid choice is entered the function (and the loop) exits with the return.
TODO
- Add winner logic to pick_winner()
