#6 Snake Game using Python (with gameplay)

 Snake Game using Python

This is very interesting and useful python project. While making this project I have learned a lot of things and function in python. In this project, there is the practice of each python basic concept. So this project is best for beginners. This project is made by using the python pygame library. So for making this project you must know little about pygame.

How to run this game on your pc only if you have installed python:

Simply click on the link given below and after the clicking, a zip file is downloaded and extract the file and you will receive and a folder named data containing some photos, music and a python file.

simply open your code editor in this data folder and run the python file and enjoy the game.

Note = Do not rename the file

Code of the game the code is also in downloadable files:
