Simple Python “Snake Game” + Code

Here’s a simple Python script for a basic Snake game using the pygame library.

You can run this code in your Python environment after installing the pygame library if you haven’t already.

pythonCopy codeimport pygame
import time
import random

# Initialize the game
pygame.init()

# Colors
white = (255, 255, 255)
yellow = (255, 255, 102)
black = (0, 0, 0)
red = (213, 50, 80)
green = (0, 255, 0)
blue = (50, 153, 213)

# Display settings
width = 600
height = 400
display = pygame.display.set_mode((width, height))
pygame.display.set_caption('Snake Game')

# Game parameters
snake_block = 10
snake_speed = 15

# Snake properties
snake_list = []
length_of_snake = 1

# Fonts
font_style = pygame.font.SysFont("bahnschrift", 25)
score_font = pygame.font.SysFont("comicsansms", 35)

    for x in snake_list:
        pygame.draw.rect(display, black, [x[0], x[1], snake_block, snake_block])

def message(msg, color):
    mesg = font_style.render(msg, True, color)
    display.blit(mesg, [width / 6, height / 3])

How to Run the Game:

Make sure you have Python installed on your computer.
Install the pygame library if you haven’t already by running:bashCopy codepip install pygame
Copy and paste the script into a Python file (e.g., snake_game.py).
Run the script using Python:bashCopy codepython snake_game.py
