Rock paper scissors has three possible outcomes: a draw, a win or a loss. A player who decides to play rock will beat another player who has chosen scissors (“rock crushes scissors” or “breaks scissors” or sometimes “blunts scissors”, but will lose to one who has played paper (“paper covers rock”); a play of paper will lose to a play of scissors (“scissors cuts paper”).
If both players choose the same shape, the game is tied and is usually immediately replayed to break the tie.
This example will use tkinter and the random libraries
- $ pip install tkinter
- $ pip install random
Code
The basic concept can be split into various sections
Create the GUI
Get the user input
Generate a random entry for the computer
Work out who has won
Create buttons and functions
# importing the required libraries and modules

import random
