Python Program For Rock Paper Scissors Game (With Code)

In this tutorial, you will learn about python program for rock paper scissors game.

This interactive game will allow users to compete against the computer, testing their luck and strategy.

Whether you’re a beginner or an experienced programmer, this project will surely keep you engaged and entertained.

So, let’s dive in and start coding!

Rock Paper Scissors is a simple hand game played between two individuals.

The game has three possible outcomes: rock beats scissors, scissors beats paper, and paper beats rock.

It is a game of chance and strategy, making it a popular choice for quick and fun competitions.

Before we dive into the code, let’s discuss the overall structure of our Python program for the Rock Paper Scissors game.

Python Program For Rock Paper Scissors Game

The program will consist of several components, including:

1. Getting user input for their move choice (rock, paper, or scissors).
2. Generating a random move for the computer.
3. Comparing the user’s move with the computer’s move to determine the winner.
4. Displaying the results to the user.
5. Offering the option to play again or exit the game.

Now that we have a clear understanding of the program’s structure, let’s start coding!

To create an interactive game, we need to get user input for their move choice.

In Python, we can achieve this using the input() function.

Let’s write the code snippet to get the user’s move:

user_move = input("Enter your move (rock, paper, or scissors): ")

By executing this code, the program will prompt the user to enter their move.

The user can input either “rock,” “paper,” or “scissors” (without the quotes).

Now that we have the user’s move, we need to generate a random move for the computer and compare the two to determine the winner.

We can accomplish this using the random module in Python.

Let’s take a look at the code.

Python Program For Rock Paper Scissors Game

import random

# Generate a random move for the computer
moves = ["rock", "paper", "scissors"]
computer_move = random.choice(moves)

# Compare the moves to determine the winner
if user_move == computer_move:
    result = "It's a tie!"
elif (user_move == "rock" and computer_move == "scissors") or (user_move == "paper" and computer_move == "rock") or (user_move == "scissors" and computer_move == "paper"):
    result = "Congratulations! You win!"
else:
    result = "Sorry, the computer wins!"

In this code snippet, we import the random module and create a list of possible moves.

We then use random.choice() to select a random move for the computer.

After that, we compare the user’s move with the computer’s move using a series of if statements.

If the conditions are met, we update the result variable accordingly.

To provide feedback to the user and display the game’s outcome, we can use the print() function. Let’s add the necessary code:

Python Program For Rock Paper Scissors Game

print(f"You chose: {user_move}")
print(f"The computer chose: {computer_move}")
print(result)

This code will print the user’s move, the computer’s move, and the result of the game (tie, user win, or computer win) on the console.

To enhance the user experience, we can add an option to play the game again.

We’ll use a while loop to achieve this. Here’s how the code will look.

Python Program For Rock Paper Scissors Game

play_again = "yes"

while play_again.lower() == "yes":
    # Game logic here
    
    play_again = input("Do you want to play again? (yes/no): ")

With this code, the game will continue as long as the user inputs “yes” when asked if they want to play again.

If the user enters “no” (or any other input), the loop will exit, and the program will terminate.

It’s essential to account for invalid user input to ensure our program runs smoothly.

Let’s add a validation check for the user’s move choice:

Python Program For Rock Paper Scissors Game

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

while user_move not in valid_moves:
    print("Invalid move. Please choose either rock, paper, or scissors.")
    user_move = input("Enter your move: ")

By implementing this code, the program will prompt the user to re-enter their move if they provide an invalid choice.

The loop will continue until the user inputs a valid move.

Here is the complete python program for the game.

import random

valid_moves = ["rock", "paper", "scissors"]
play_again = "yes"

while play_again.lower() == "yes":
    user_move = input("Enter your move (rock, paper, or scissors): ")
    
    while user_move not in valid_moves:
        print("Invalid move. Please choose either rock, paper, or scissors.")
        user_move = input("Enter your move: ")
        
    moves = ["rock", "paper", "scissors"]
    computer_move = random.choice(moves)

    if user_move == computer_move:
        result = "It's a tie!"
    elif (user_move == "rock" and computer_move == "scissors") or (user_move == "paper" and computer_move == "rock") or (user_move == "scissors" and computer_move == "paper"):
        result = "Congratulations! You win!"
    else:
        result = "Sorry, the computer wins!"
        
    print(f"You chose: {user_move}")
    print(f"The computer chose: {computer_move}")
    print(result)
    
    play_again = input("Do you want to play again? (yes/no): ")

Output

How can I run the Python program for the Rock Paper Scissors game?

To run the program, you need to have Python installed on your computer.

Save the code with a .py extension, open a command prompt or terminal, navigate to the file’s directory, and type python filename.py (replace “filename” with the actual name of your file).

Press Enter, and the game will start.

Can I modify the program to add more moves, such as “lizard” and “spock”?

Absolutely! The program’s logic can be extended to include additional moves.

You would need to update the list of valid moves, adjust the comparison conditions, and display the results accordingly.

How can I make the game more challenging?

You can introduce elements such as keeping track of the user’s and computer’s scores, adding a time limit for decision-making, or implementing an AI opponent with various difficulty levels.

Is there a limit to the number of times I can play the game?

No, there is no predefined limit. You can play the game as many times as you like by choosing to play again after each round.

Can I create a graphical user interface (GUI) for this game?

Yes, you can! Python provides several GUI libraries like Tkinter, PyQt, and Pygame that can be used to create an interactive interface for the game.

Congratulations! You have successfully learned how to create a Python program for the Rock Paper Scissors game.

This project allowed you to practice user input, randomization, conditional statements, and loops.
