Snake Game

How to Create a Snake Game using Python

Create a Snake Game using Python

It’s time to code a game in Python. Hello coder, welcome to the codewithrandom blog. In this article, we create a Snake Game using Python Programming with Complete Source Code. We will start with a most popular Snake Game  where the player controls a snake that moves around a screen and tries to eat food while avoiding the walls and its own tail. In Python, the Snake game can be implemented using the tkinter , which provides an easy way to create interactive 2D games.

Project Requirements

In this Snake Game project We need to import random & tkinter  module.

from tkinter import *
import random

To play the Snake game in Python, you can follow these steps:

  1. open any python code Editor.
  2. Import  the required  module .
  3. Copy the code for the Snake game implementation in Python, which I provided Below in this article, and save it in a file named “” (or any other name you prefer).
  4.  Run this  python file to start the game.
  5. Use the arrow keys on your keyboard to move the snake around the screen and try to eat the food without running into the walls or the snake’s own tail.

That’s it! Have fun playing the Snake game in Python.
