How to create Snake Game Using Python | Free Python Project with source code

Hey welcome to coding surfer in  this instructional exercise you will figure out how to construct the game snake. The game is an snake game and it has exceptionally straightforward rationale, which is the reason it is a perfect guide to show how to manufacture games with Pygame. And  you can download this game from link given below in the website.

 

The player is spoken to as snake, which develops in the event that it eats an apple. The objective of the game is to eat whatever number apples as could be expected under the circumstances without crashing into yourself. This is simple in the early period of the game yet is progressively increasingly troublesome as the length of the snake develops.

We need to create this snake game -

• Pygame 
• Random

Command for installing these module's -

• pip install pygame

• Random - pre-installed

Code for creating snake game -
