  • Paper covers Rock

To implement this in Python, you will need to use the `random` module to allow the computer to make a random choice.

Implementing the Game

Below is a simple implementation of the Rock Paper Scissors game in Python:

“`python
import random

def get_computer_choice():
options = [‘rock’, ‘paper’, ‘scissors’]
return random.choice(options)

def get_user_choice():
user_input = input(“Enter rock, paper, or scissors: “).lower()
while user_input not in [‘rock’, ‘paper’, ‘scissors’]:
print(“Invalid choice. Please choose again.”)
user_input = input(“Enter rock, paper, or scissors: “).lower()
return user_input

def determine_winner(user_choice, computer_choice):
if user_choice == computer_choice:
return “It’s a tie!”
elif (user_choice == ‘rock’ and computer_choice == ‘scissors’) or \
(user_choice == ‘scissors’ and computer_choice == ‘paper’) or \
(user_choice == ‘paper’ and computer_choice == ‘rock’):
return “You win!”
else:
return “You lose!”

def play_game():
user_choice = get_user_choice()
computer_choice = get_computer_choice()
print(f”You chose: {user_choice}”)
print(f”Computer chose: {computer_choice}”)
result = determine_winner(user_choice, computer_choice)
print(result)

if __name__ == “__main__”:
play_game()
“`
