Question

In python language

Write a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows: 1. When the program begins, a random number in the range of 1 and 3 is generated. 1 = Computer has chosen Rock 2 = Computer has chosen Paper 3 = Computer has chosen Scissors (Dont display the computer's choice yet) 2. The user enters his or her choice of “Rock”, “Paper", “Scissors" at the keyboard. 3. The computer's choice is displayed. 4. A winner is selected according to the following rules: a. Rock smashes Scissors b. Scissors cuts Paper c. Paper wraps rock d. If both players make the same choice, the game must be played again to determine the winner. When writing this program, create your own functions. You must also have at least one value returning function. Deliverables: 1. A well-documented working python program (.py file) Sample Output: Enter 1 for rock, 2 for paper, 3 for scissors: 1 Computer chose rock You chose rock You made the same choice as the computer. Starting over Enter 1 for rock, 2 for paper, 3 for scissors: 2 Computer chose scissors You chose paper The computer wins the game

Answer 1

Here is the python code to the given question.

Two sample outputs are added at the end.

Code:

import random

    Returns:
    
    Boolean : True if user wins and False if computer wins.
    
    """
    
    if  (userChoice==1 and computerChoice==3) or (userChoice==2 and computerChoice==1) or(userChoice==3 and computerChoice==2):

if __name__=="__main__":
    
    main()   #calls main
