How to Create a Python Snake Game in 30 Seconds!

In this tutorial, we'll create a simple Snake Game using Python. If you're a beginner or looking for a fun project, this game is perfect. Follow the steps below, copy the code, and start coding right away!

Step 1: Install pygame

To begin, you'll need to install the pygame library. Open your terminal or command prompt and run the following command:

pip install pygame

This will install the required library to run the game.

Step 2: Copy the Snake Game Code

Once you’ve installed pygame, copy the code below and paste it into a Python file (for example, snake_game.py).

Python Snake Game Code:

import pygame
import time
import random

# Initialize pygame
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)

# Window size
width = 600
height = 400
display = pygame.display.set_mode((width, height))

# Game title
pygame.display.set_caption('Snake Game')

# Clock and speed
clock = pygame.time.Clock()
snake_speed = 15
snake_block = 10

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

# Score function
def your_score(score):
    value = score_font.render(f"Your Score: {score}", True, yellow)
    display.blit(value, [0, 0])

# Snake function
def our_snake(snake_block, snake_list):
    for x in snake_list:
        pygame.draw.rect(display, green, [x[0], x[1], snake_block, snake_block])

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

# Game loop
def gameLoop():
    game_over = False
    game_close = False

    x1 = width / 2
    y1 = height / 2

    # Set initial movement so the snake moves at the start
    x1_change = snake_block
    y1_change = 0

    snake_list = []
    length_of_snake = 1

    foodx = round(random.randrange(0, width - snake_block) / 10.0) * 10.0
    foody = round(random.randrange(0, height - snake_block) / 10.0) * 10.0

    while not game_over:

        while game_close:
            display.fill(blue)
            message("You Lost! Press C-Play Again or Q-Quit", red)
            your_score(length_of_snake - 1)
            pygame.display.update()

            for event in pygame.event.get():
                if event.type == pygame.KEYDOWN:
                    if event.key == pygame.K_q:
                        game_over = True
                        game_close = False
                    if event.key == pygame.K_c:
                        gameLoop()

        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                game_over = True
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_LEFT:
                    x1_change = -snake_block
                    y1_change = 0
                elif event.key == pygame.K_RIGHT:
                    x1_change = snake_block
                    y1_change = 0
                elif event.key == pygame.K_UP:
                    y1_change = -snake_block
                    x1_change = 0
                elif event.key == pygame.K_DOWN:
                    y1_change = snake_block
                    x1_change = 0

        if x1 >= width or x1 < 0 or y1 >= height or y1 < 0:
            game_close = True
        x1 += x1_change
        y1 += y1_change
        display.fill(black)
        pygame.draw.rect(display, white, [foodx, foody, snake_block, snake_block])
        snake_head = []
        snake_head.append(x1)
        snake_head.append(y1)
        snake_list.append(snake_head)
        if len(snake_list) > length_of_snake:
            del snake_list[0]

        for x in snake_list[:-1]:
            if x == snake_head:
                game_close = True

        our_snake(snake_block, snake_list)
        your_score(length_of_snake - 1)

        pygame.display.update()

        if x1 == foodx and y1 == foody:
            foodx = round(random.randrange(0, width - snake_block) / 10.0) * 10.0
            foody = round(random.randrange(0, height - snake_block) / 10.0) * 10.0
            length_of_snake += 1

        clock.tick(snake_speed)

    pygame.quit()
    quit()

# Start the game
gameLoop()
  

Step 3: Run the Game

Once you've copied the code and saved it in a Python file, run it by using this command in your terminal:

python snake_game.py

Use the arrow keys to control the snake, eat the food, and grow. Avoid hitting the walls or yourself!

Enjoy Coding!

This is a fun and quick project to practice Python programming and game development. Feel free to experiment by adjusting the speed, colors, or adding new features. Happy coding!
