How to implement Snake Game In Python
To properly implement the snake game in python, open a new project, and give it a name of your choice. In that project, we shall have 5 independent files that will coordinate together to implement the snake game. Open five new files and label them as
- py – this file contains the main gameplay of the snake game. This is the file that the player essentially runs in their Pycahrm Code Editor for the game to start.
- py – the game we develop here can either be a mono – player or dual – player. The essence of the menu is to help the player determine which game mode they intend to play.
- py – this file will contain ode that is responsible for the creation and response behavior of
the snake during game play.
- py – responsible for keeping track of scores and high scores
- py – this file contains code that describes the appearance, position, and behavior of the snake food as it interacts with the snake segments.
