Python rock Paper Scissors Game

In this article we’ll learn how to create a Python Rock Paper Scissors Game. Rock paper scissors game is also known as stone paper scissors. It is a hand game that is usually played between 2 people, each player can randomly form any one of three from their hand.

A player who chooses rock will win by another player who chooses scissors but loose by the player who chooses paper; a player with paper will loose by the player with the scissors.

If both players choose the same then the game is tied. Rock paper scissors game is mainly played among kids.

Rock-Paper-Scissors Game Python Project

The object of the rock-paper-scissor python project is to build a game for a single player that plays with a computer, anywhere, and anytime. This project is base on the rules that:

  • rock blunts scissors so rock wins
  • scissors cut the paper so scissors win
  • paper cover rock so paper wins

This project is build using tkinter, random modules, and the basic concept of python.

In this project, players have to choose any one from rock, paper, and scissors. Then click on the play button will show the result of the game.

Project Prerequisites

To implement this python rock paper scissors project we will use the basic concept of python with tkinter and random module.

  • Tkinter is a standard GUI library which is one of the easiest ways to build a GUI application.
  • random module use to generate random numbers

To install the libraries we can use the pip installer command on the command prompt:

pip install tkinter pip install random
Code language: Python (python)

Project File Structure

These are the step to build a rock-paper-scissors game using python:

  • Import required libraries
  • Initialize window
  • Code for user choice
  • Code for computer choice
  • Define functions
  • Define buttons

Let’s start

1. Importing Libraries

from tkinter import * import random
Code language: Python (python)

The first step is to import libraries. Here, we required two modules so we need to import Tkinter and random modules.

2. Initialize Window

root = Tk() root.geometry('400x400') root.resizable(0,0) root.title('Techarge-Rock,Paper,Scissors') root.config(bg ='seashell3')
Code language: Python (python)
  • Tk() use to initialized Tkinter to create window
  • geometry() sets the window width and height
  • resizable(0,0) by this command we can fix the size of the window
  • title() used to set the title of the window
  • bg = ‘’ use to set the color of the background
Label(root, text = 'Rock, Paper ,Scissors' , font='arial 20 bold', bg = 'seashell2').pack()
Code language: Python (python)
  • Label() widget used when we want to display text that users can’t modify.
  • root is the name of our window
  • text which displays on the label as the title of that label
  • font in which form the text is written
  • pack used to the organized widget in form of block

3. For User Choice

user_take = StringVar() Label(root, text = 'choose any one: rock, paper ,scissors' , font='arial 15 bold', bg = 'seashell2').place(x = 20,y=70) Entry(root, font = 'arial 15', textvariable = user_take , bg = 'antiquewhite2').place(x=90 , y = 130)
Code language: Python (python)
  • user_take is a string type variable that stores the choice that the user enters.
  • Entry() widget used when we want to create an input text field.
  1. textvariable used to retrieve the text to entry widget
  2. place() – place widgets at specific position

4. For Computer Choice

comp_pick = random.randint(1,3) if comp_pick == 1: comp_pick = 'rock' elif comp_pick ==2: comp_pick = 'paper' else: comp_pick = 'scissors'
Code language: PHP (php)

random.randint() function will randomly take any number from the given number.

Here we give the if-else() condition to play rock paper scissors

  • If the computer choose 1 then the rock will set to comp_pick variable
  • If the computer choose 2 then the paper will set to comp_pick variable
  • If the computer choose 3 then scissors will set to comp_pick variable

5. Function to Start Game

Result = StringVar() def play(): user_pick = user_take.get() if user_pick == comp_pick: Result.set('tie,you both select same') elif user_pick == 'rock' and comp_pick == 'paper': Result.set('you loose,computer select paper') elif user_pick == 'rock' and comp_pick == 'scissors': Result.set('you win,computer select scissors') elif user_pick == 'paper' and comp_pick == 'scissors': Result.set('you loose,computer select scissors') elif user_pick == 'paper' and comp_pick == 'rock': Result.set('you win,computer select rock') elif user_pick == 'scissors' and comp_pick == 'rock': Result.set('you loose,computer select rock') elif user_pick == 'scissors' and comp_pick == 'paper': Result.set('you win ,computer select paper') else: Result.set('invalid: choose any one -- rock, paper, scissors')
Code language: PHP (php)

6. Function to Reset

  • user_take is a string type variable that stores the choice that the user enters.
  • We give if-else() condition to check who wins between user choice and computer choice.
  • In this rock paper scissors game,  a player who chooses rock will win by another player who chooses scissors but loose by the player who chooses paper; a player with paper will loose by the player with the scissors. If both choose the same then the game will tie.
def Reset(): Result.set("") user_take.set("")
Code language: Python (python)

7. Function to Exit

This function set all variables to an empty string.

def Exit(): root.destroy()
Code language: Python (python)

root.destroy() will quit the rock paper scissors program by stopping the mainloop().
