Question

Write a program in python that lets the user play the game Rock, Paper, Scissors against the computer. The program should work as follows:

• When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. 2 corresponds to paper, and 3 corresponds to scissors.
• To set up the random number library, write the following at the top of your code:

import random
random.seed(300)

• Use number = random.randint(1, 100) to generate your random numbers
• The user chooses rock, paper, scissors, or to exit the game. Tell the user to enter 1-3 for their choice and input it as a number, or 4 if they want to exit.
• Begin a while loop for the game that exits if they chose 4.
• The computer's choice is displayed, mapping its numerical choice to the correct string (use if statements).
• The player's choice is displayed.
• A winner is selected and outputted using the following rules:
  • Rock beats scissors
  • Scissors beats paper
  • Paper beats rock
  • If both players make the same choice, it is a tie.
• The program generates a new computer choice, asks the user for a new menu choice, and loops to play a new game if they didn't select 4 to exit.

Use the following functions in your design. They will be unit tested:

getPlayerChoice() 

• print menu to ask user choice and return as Integer

getComputerChoice()

• generate random computer choice and return as Integer

determineWinner(computerChoice, playerChoice)

• Compare the two choices and return a string, containing one of the following:
  • "Player wins!"
  • "Computer wins!"
  • "Tie!"
• Use its return value to print the winner of the game.

convertChoice(choice); 

• return "rock", "paper", or "scissors" as a string, depending on the Integer parameter. Use its return value to print the player or the computer's choice.

main()

• main function that will contain your game loop and call the other functions
• For main to execute properly when your script runs, the Python interpreter will need this statement at the end of your file:

if __name__ == '__main__':
    main()

Your file main.py will look like this:

import random
random.seed(300)

def determineWinner(playerChoice, computerChoice):
    ```statements```

def convertChoice(choice):
    ```statements```

def getComputerChoice():
    ```statements```

def getPlayerChoice():
    ```statements```

# Main
def main():
    #get the player choice
    #generate the computer choice
    #while the user has not chosen 4
        #print the player choice as a string
        #print the computer choice as a string
        #print the winner as a string
        #get new choices for the player and computer

if __name__ == '__main__':
    main()

Answer 1

import random

random.seed(300)

def determineWinner(playerChoice, computerChoice):
    # Check who won and print
    if computerChoice == 1 and playerChoice == 2:
        return "Player wins!"
    elif computerChoice == 2 and playerChoice == 1:
        return "Computer wins!"
    elif computerChoice == 3 and playerChoice == 1:
        return "Player wins!"
    elif computerChoice == 1 and playerChoice == 3:
        return "Computer wins!"
    elif computerChoice == 2 and playerChoice == 3:
        return "Player wins!"
    elif computerChoice == 3 and playerChoice == 2:
        return "Computer wins!"
    else:
        return "Tie!"

def convertChoice(choice):
    # Return respective value to number
    if choice == 1:
        return 'rock'
    elif choice == 2:
        return 'paper'
    else:
        return 'scissors'

def getComputerChoice():
    return random.randint(1, 3)

def getPlayerChoice():
    # Ask user to enter either of four
    choice = int(input('1. rock, 2. paper, 3. scissors or 4 to exit: '))
    # Keep asking till user enters a valid input
    while choice not in [1, 2, 3, 4]:
        choice = int(input('1 .rock, 2. paper, 3. scissors or 4 to exit: '))

    return choice


# Main
def main():
    player = getPlayerChoice()  # get the player choice
    comp = getComputerChoice()  # generate the computer choice
    while player != 4:  # while the user has not chosen 4
        # print the player choice as a string
        print('Player''s Choice:', convertChoice(player))
        # print the computer choice as a string
        print('Computer''s Choice:', convertChoice(comp))
        # print the winner as a string
        print(determineWinner(player, comp))

        print()
        # get new choices for the player and computer
        player = getPlayerChoice()
        comp = getComputerChoice()


if __name__ == '__main__':
    main()
