Code Snippet

import random

# Function below is to get and validate user's choice
def get_user_choice():
    # Convert user's choice to lowercase
    user_choice = input("Enter your choice (rock, paper, or scissors): ").lower()

   # Validate it is either "rock", "paper", or  "scissors"
    while user_choice not in ["rock", "paper", "scissors"]:
        print("Invalid choice. Please insert either rock, paper, or scissors.")
        # If invalid, prompt the following for user choice
        user_choice = input("Enter your choice (rock, paper, or scissors): ").lower()
    return user_choice

# Function below is to generate computer's choice randomly
def generate_computer_choice():
    return random.choice(["rock", "paper", "scissors"])

# Function below is to determine who is the winner of the game
def determine_winner(user_choice, computer_choice):
    print(f"You chose {user_choice}.")
    print(f"Computer chose {computer_choice}.")

    if user_choice == computer_choice:
        return "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")
    ):
        return "You win!"
    else:
        return "Computer wins!"

def main():
    print("Welcome to Rock, Paper, Scissors Game!")
    user_choice = get_user_choice()
    computer_choice = generate_computer_choice()
    result = determine_winner(user_choice, computer_choice)
