snake game in python

To create a snake game in Python, we'll use Pygame, which is a great game library for Python programming. Pygame provides a set of functions and tools to help us build games easily.

To start, we'll need to install Pygame using pip. Open a command prompt and type the following command:

main.py
pip install pygame
19 chars
2 lines

Once installed, we should import the library in our Python script:

main.py
import pygame
14 chars
2 lines

Next, we'll create a Pygame window and set its size:

main.py
WIDTH = 500
HEIGHT = 500
window = pygame.display.set_mode((WIDTH, HEIGHT))
75 chars
4 lines

We'll also need to set the title of the window:

main.py
pygame.display.set_caption("Snake Game")
41 chars
2 lines

Now, we can create the main loop of the game. This loop will run until the player exits the game. We can exit the game by either clicking the close button or pressing the ESC key.

main.py
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT or event.type == pygame.KEYDOWN and event.key == pygame.K_ESCAPE:
            running = False
198 chars
6 lines

Inside the main loop, we can update the game logic and redraw the screen. We'll need to create the snake and the food. We'll also need to check for collisions between the snake and the food and with the walls.

Here's the basic structure of the game loop:

main.py
while running:
    # handle events
    for event in pygame.event.get():
        if event.type == pygame.QUIT or event.type == pygame.KEYDOWN and event.key == pygame.K_ESCAPE:
            running = False
    
    # update game logic
    
    # draw screen
    
    pygame.display.update()
288 chars
12 lines

This is just a basic outline of the game. To implement the full game, we'll need to create the Snake and Food classes, and add keyboard controls to move the snake.

I hope this helps you get started with creating a snake game in Python using Pygame library.
