Python Program For Rock Paper Scissors (With Code)

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

Rock paper scissors is a popular hand game played by people of all ages.

Whether you’re settling a decision or just having fun, this game never fails to entertain.

In this article, we will explore how to create a Python program for rock paper scissors.

By following the code examples and explanations provided, you’ll be able to play this game against a computer opponent.

Rock paper scissors, also known as “Ro-Sham-Bo,” is a simple hand game played between two people.

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

The objective is to select an option that defeats the choice made by the opponent.

This classic game is often used to settle disputes or make decisions in a fair and random manner.

Getting Started: Python Program For Rock Paper Scissors

Before diving into the creation of the rock paper scissors program, let’s ensure that you have Python installed on your system.

If not, you can download and install Python.

Or conveniently use our free and state of the art online python compiler.

Now, you’re ready to begin.

Now let’s walk through the step-by-step process of creating a Python program for rock paper scissors.

By the end of this section, you’ll have a functional program that allows you to play this game against a computer opponent.

Step 1: Importing Required Libraries

To get started, we need to import the random module in Python, which will help us generate the computer’s choice randomly.

Here’s how you can do it.

import random

Step 2: Defining the Game Logic

Next, we’ll define the logic for the game. In rock paper scissors, each option has a numeric value associated with it: rock is 1, paper is 2, and scissors is 3.

We’ll create variables to store these values:

rock = 1
paper = 2
scissors = 3

Step 3: Taking User Input

Now, let’s write code to take input from the user.

We’ll use the input() function to prompt the user for their choice:

user_choice = int(input("Enter your choice (1 - Rock, 2 - Paper, 3 - Scissors): "))

Step 4: Generating Computer’s Choice

To determine the computer’s choice, we’ll use the random.randint() function.

This function generates a random integer within a specified range.

In our case, we want a random number between 1 and 3:

computer_choice = random.randint(1, 3)

Step 5: Determining the Winner

Now, it’s time to determine the winner based on the choices made by the user and the computer.

We’ll use a series of conditional statements to compare the choices and decide the outcome.

Python Program For Rock Paper Scissors

if user_choice == rock and computer_choice == scissors:
    print("You win! Rock beats scissors.")
elif user_choice == paper and computer_choice == rock:
    print("You win! Paper beats rock.")
elif user_choice == scissors and computer_choice == paper:
    print("You win! Scissors beat paper.")
elif user_choice == computer_choice:
    print("It's a tie!")
else:
    print("You lose! Try again.")

Step 6: Playing the Game

To play the game continuously, we can put the code inside a loop.

Here’s an example of how you can accomplish this.

Python Program For Rock Paper Scissors

while True:
    user_choice = int(input("Enter your choice (1 - Rock, 2 - Paper, 3 - Scissors): "))
    computer_choice = random.randint(1, 3)
    
    # Rest of the game logic code here
    
    play_again = input("Do you want to play again? (y/n): ")
    if play_again.lower() != "y":
        break

Congratulations! You’ve successfully created a Python program for rock paper scissors.

Now you can challenge the computer and enjoy this classic game whenever you want.

Here is the complete Python program for rock paper scissors.

import random

rock = 1
paper = 2
scissors = 3

user_score = 0
computer_score = 0

while True:
    user_choice = int(input("Enter your choice (1 - Rock, 2 - Paper, 3 - Scissors): "))
    computer_choice = random.randint(1, 3)
    
    if user_choice == rock and computer_choice == scissors:
        print("You win! Rock beats scissors.")
        user_score += 1
    elif user_choice == paper and computer_choice == rock:
        print("You win! Paper beats rock.")
        user_score += 1
    elif user_choice == scissors and computer_choice == paper:
        print("You win! Scissors beat paper.")
        user_score += 1
    elif user_choice == computer_choice:
        print("It's a tie!")
    else:
        print("You lose! Try again.")
        computer_score += 1
    
    print("User Score:", user_score)
    print("Computer Score:", computer_score)
    
    play_again = input("Do you want to play again? (y/n): ")
    if play_again.lower() != "y":
        break

Output

Q: Can I modify the program to add more options?

Absolutely! You can expand the program by adding more options like “Lizard” and “Spock” to make it a more advanced version of the game.

Just remember to update the numeric values associated with each choice accordingly.

Q: How do I make the computer’s choice random?

The random.randint() function we used generates a random integer within a given range.

By adjusting the range, you can control the options available for the computer.

For example, if you have five options, you can change the range to random.randint(1, 5).

Q: Can I play against another player instead of the computer?

Certainly! Instead of generating the computer’s choice randomly, you can prompt the second player for their input and compare the choices to determine the winner.

Q: Is there a way to keep track of scores?

Yes, you can implement a scoring system by creating variables to track the number of wins, losses, and ties. Increment the corresponding variable based on the outcome of each round and display the final scores at the end of the game.

Q: How do you write rock paper scissors code in Python?

To write rock paper scissors code in Python, you can follow these steps:

1. Import the required libraries, such as the random module.
2. Define the game logic by assigning numeric values to rock, paper, and scissors.
3. Take user input for their choice using the input() function.
4. Generate the computer’s choice using the random.randint() function.
5. Compare the choices using conditional statements to determine the winner.
6. Play the game continuously by putting the code inside a loop.

Q: How does rock paper scissors work in Python?

In Python, rock paper scissors works by taking input from the user and generating a random choice for the computer.

The user’s input and the computer’s choice are then compared using conditional statements to determine the winner based on the game’s rules: rock beats scissors, scissors beat paper, and paper beats rock.

Q: How to make a rock paper scissors game in Python with score?

To make a rock paper scissors game in Python with a score, you can introduce variables to keep track of the number of wins, losses, and ties. Increment the corresponding variable based on the outcome of each round and display the final scores at the end of the game.

You can also add a scoring system within the loop to continuously update the scores as the game progresses.

Q: What is the logic in Rock Paper Scissors?

The logic in rock paper scissors is based on a set of conditional statements that compare the choices made by the user and the computer.

The outcome of the game is determined by the following rules: rock beats scissors, scissors beat paper, and paper beats rock.

By evaluating these conditions, the program can identify the winner and display the result accordingly.

In this tutorial, we learned how to create a Python program for rock paper scissors.

By following the step-by-step guide and code examples provided, you can now enjoy playing this classic game against a computer opponent.

Feel free to customize and expand the program to make it even more engaging.

Happy Coding!
