Rock Paper Scissors Game in Python

Rock Paper Scissors Game in Python

Hello folks! Today, we are back with a fantastic tutorial on the Rock Paper Scissors Game in Python. We all are familiar with the topic that we have chosen for today’s tutorial. We all played this game with our friends during our childhood time. Basically, we used to use our hand gestures in order to show the shapes of rock, paper, and scissors. On the other hand, there will be another player who will go on with the same gestures. We usually used to play this game thrice and then decide the winner accordingly.

Imagine building this in Python; you will have a game to play whenever you are bored. So let us start our article and make this project. We will start with getting an overview and then talk about a complete code explanation. Now, let us move on to getting an idea for the Rock Paper Scissors Game in Python.

Basic Idea

Here, we will convert this hand gesture-based game into a game that can be played with a computer. All game rules will be the same as they will be, but we will keep track of the scores of both players in digital format. Let us check the list of superiority among the three objects in the Rock, Paper, and Scissor Game in Python.

  • Rock < Paper
  • Paper < Scissor
  • Scissor < Rock

Features of Rock Paper Scissors Game in Python

Below are some of the features that we need to have in our Rock Paper and Scissor Game

  • Display 3 options for the user to choose from, namely, Rock, Paper, and Scissors
  • Display live score counter of user and PC
  • Feature to allow the user to add his/her name in Rock Paper and Scissor Game

Complete Code for the Rock Paper Scissors Game in Python

We have used comments to explain the code.

#importing the basic library that we will use for the development of this project
from tkinter import *
from PIL import Image,ImageTk
import random

#these are some of the variables that we will use in rock paper and scissor game
userscore=0
pcscore=0


#these are various function that will help us to handle all the events that will take place in this project
#we also used the config() function to configure the various widgets like its color, size etc
def enter(event):
    rock.config(bg='black',fg='white')
def enter1(event):
    paper.config(bg='black',fg='white')
def enter2(event):
    scissor.config(bg='black',fg='white')
def leave(event):
    rock.config(bg='white',fg='black')
def leave1(event):
    paper.config(bg='white',fg='black')
def leave2(event):
    scissor.config(bg='white',fg='black')
def entergame(event):
    maingame()

#Maingame Function will bring a new window of GUI and will provide a platform to play rock paper and scissor Game
