Question

Rock, Paper, Scissors Game
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 through 3 is generated.
If the number is 1, then the computer has chosen rock. If the number is 2, then
the computer has chosen paper. If the number is 3, then the computer has chosen
scissors. (Don’t display the computer’s choice yet.)
2. The user enters his or her choice of “rock”, “paper”, or “scissors” at the keyboard.
(You can use a menu if you prefer.)
3. The computer’s choice is displayed.
4. A winner is selected according to the following rules:
• If one player chooses rock and the other player chooses scissors, then rock wins.
(The rock smashes the scissors.)
• If one player chooses scissors and the other player chooses paper, then scissors
wins. (Scissors cuts paper.)
• If one player chooses paper and the other player chooses rock, then paper wins.
(Paper wraps rock.)
• If both players make the same choice, the game must be played again to determine
the winner.
Be sure to divide the program into functions that perform each major task.

# Introduction to the game. Give instructions.

    print('Rock. Paper. Scissors.' ' ' 'Enter 1 for Rock, 2 for Paper or 3 for Scissors.', ' ')
    enter_player_answer()

# Generate random integers.

# Function that gets player choice with validation loop.

    player = int(input('Enter your choice: '))
# Input validation loop.
    while player != 1 and player != 2 and player != 3:
        print('Invalid entry. Please try again.')
        player = int(input('Enter 1, 2, or 3.: '))
    display_computer_answer(player)

# Function that displays computer answer.

    c_answer = generate_random_int()
    print('Computer picks: ', c_answer, ' ')
    determine_winner(c_answer, player)

#Function that determines the winner.

    if c == p:
        print('Try again.')
        enter_player_answer()
    elif c == 1 and p == 2:
