Question

Write a Python program (rock_paper_scissors.py) that allows two players play the game rock paper scissors.

Remember the rules:

1. Rock beats scissors

2. Scissors beats paper

3. Paper beats rock

The program should ask the users for their names, then ask them for their picks (rock, paper or scissors). After that, the program should print the winner's name. Note, the players may pick the same thing, in this case the program should say it's tie. when the user input an invalid choice, the program should inform the user.

Your program should contain two functions:

(1) compare_answers(u1, u1a, u2, u2a): This function takes four parameters (u1, u1a, u2, u2a), and returns a string. The parameters are all strings: u1(player 1 name), u1a (player 1 choice), u2 (player 2 name), and u2a(player 2 choice). The returned string should include the result of the game. (Submit for 6 points)

For example:

1. It's a tie!

2. Invalid input! You have not entered rock, paper or scissors, try again.

3. Rock wins! Good job 'u1'

4. Scissors win! Good job u2

(2) __main__: In the main, you do the following: (Submit for 4 points)

a. Prompt the user to input the name of player 1.

b. Prompt the user to input the name of player 2.

c. Prompt the user to input the choice of player 1.

d. Prompt the user to input the choice of player 2.

e. Print the result of the game.

Here are some example runs of the program:

Example 1: Player 1 inputs an invalid choice.

# FIXME 1: Complete the compare_answers function
def compare_answers(u1, u1a, u2, u2a):
    if u1a == u2a:
        pass
    elif u1a == 'rock':
        if u2a == 'scissors':
            return("Rock wins! Good job " + u1)
        elif u2a == 'Paper':
            pass
        else:
            pass
    
    # You need more elif in here
    
    else:
        pass


if __name__ == "__main__":
    # FIXME 2a: Prompt the user to input the name of player 1
    pass
    # FIXME 2b: Prompt the user to input the name of player 2

    # FIXME 2c: Prompt the user to input the choice of player 1

    # FIXME 2d: Prompt the user to input the choice of player 2

    # FIXME 2e: Call the function and print the result of the game
