Beginner Python: Rock, Paper, Scissors Code

Here’s a simple Python program to play Rock, Paper, Scissors:

pythonCopy codeimport random

def play_game():
    choices = ['rock', 'paper', 'scissors']
    computer_choice = random.choice(choices)

    user_choice = input("Enter rock, paper, or scissors: ").lower()

    if user_choice not in choices:
        print("Invalid choice! Please choose rock, paper, or scissors.")
        return

    print(f"Computer chose: {computer_choice}")

    if user_choice == computer_choice:
        print("It's a tie!")
    elif (user_choice == 'rock' and computer_choice == 'scissors') or \
         (user_choice == 'paper' and computer_choice == 'rock') or \
         (user_choice == 'scissors' and computer_choice == 'paper'):
        print("You win!")
    else:
        print("You lose!")

if __name__ == "__main__":
    play_game()

How It Works:

Import the random module: This is used to allow the computer to randomly select its choice.
Define the play_game function: This function handles the game logic.
User Input: The user is prompted to enter their choice.
Computer Choice: The computer randomly picks rock, paper, or scissors.
Determine the Outcome: The program compares the user’s choice with the computer’s choice and prints out the result.
Main Check: The program runs the play_game function when executed.
