Paper, Scissors Game in Python – Full Tutorial

🎮 Build a Rock, Paper, Scissors Game in Python

Welcome back to DarchumsTech! In today’s tutorial, we’re going to build a classic game — Rock, Paper, Scissors. You’ll learn how to work with conditionals, loops, and random choices in Python.

---

🧠 What You’ll Learn

• Using the random module
• Working with conditionals and loops
• Creating interactive input-based games

🚀 Step 1: Import and Setup

import random

choices = ["rock", "paper", "scissors"]

We import the random module to let the computer randomly choose its move.

🕹️ Step 2: Build the Game Logic

while True:
    user_choice = input("Enter rock, paper, or scissors (or 'quit' to stop): ").lower()
    if user_choice == "quit":
        print("Thanks for playing!")
        break
    if user_choice not in choices:
        print("Invalid input. Try again.")
        continue

    computer_choice = random.choice(choices)
    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!")

🎯 How It Works

• The user inputs their move.
• The computer randomly picks a move.
• The program compares both and declares a winner.

🎮 Sample Gameplay

Enter rock, paper, or scissors (or 'quit' to stop): rock
Computer chose: scissors
You win!

Enter rock, paper, or scissors (or 'quit' to stop): scissors
Computer chose: rock
You lose!

Enter rock, paper, or scissors (or 'quit' to stop): quit
Thanks for playing!

🔁 Bonus: Score Counter

Let’s keep track of your score!

user_score = 0
computer_score = 0

while True:
    user_choice = input("Enter rock, paper, or scissors (or 'quit'): ").lower()
    if user_choice == "quit":
        print(f"Final Score — You: {user_score}, Computer: {computer_score}")
        break

    if user_choice not in choices:
        print("Invalid input.")
        continue

    computer_choice = random.choice(choices)
    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!")
        user_score += 1
    else:
        print("You lose!")
        computer_score += 1

🏁 Wrap Up

• This game teaches logic, conditionals, and loops in a fun way.
• You can expand it with GUI, multiplayer, or sound effects.
