Step-by-Step Python Implementation of the Classic Snake Game Using Pygame

The article begins by recalling the classic Nokia Snake game and introduces a Python project that recreates it using the Pygame library. It specifies the development environment: Python 3, Windows OS, and the Pygame module (installable via pip install pygame ).

An example screenshot of the running game is shown, followed by a detailed code listing that implements the game logic. The code defines constants for window size, cell size, colors, and directions, and includes functions for distance calculation, movement validation, direction updates, and AI-like decision making. The main game loop handles event processing, apple placement, worm growth, collision checks, and rendering of the grid, worm, apple, and score.

Additional helper functions manage the start screen, game‑over screen, score display, and random apple placement. The program runs by calling main() when the script is executed directly. Overall, the tutorial provides a comprehensive, ready‑to‑run example for anyone interested in learning Python game development.
