Python 贪吃蛇游戏：入门级代码实现

以下是一个基本的 Python 贪吃蛇游戏的代码，您可以使用方向键控制蛇的移动。如果蛇撞到边界或自己，游戏将结束。如果蛇吃到食物，将会在控制台上输出'Yummy!!'。

import pygame
import time
import random

ppygame.init()

white = (255, 255, 255)
black = (0, 0, 0)
red = (213, 50, 80)
green = (0, 255, 0)
blue = (50, 153, 213)

dis_width = 600
dis_height = 400

dis = pygame.display.set_mode((dis_width, dis_height))
ppygame.display.set_caption('Snake Game by Pythonist')

clock = pygame.time.Clock()

snake_block = 10
snake_speed = 15

font_style = pygame.font.SysFont(None, 30)

def message(msg, color):
    mesg = font_style.render(msg, True, color)
    dis.blit(mesg, [dis_width / 6, dis_height / 3])

def gameLoop():
    game_over = False
    game_close = False

    x1 = dis_width / 2
    y1 = dis_height / 2

    x1_change = 0
    y1_change = 0

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

    while not game_over:

        while game_close == True:
            dis.fill(black)
            message('You Lost! Press Q-Quit or C-Play Again', red)
            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 >= dis_width or x1 < 0 or y1 >= dis_height or y1 < 0:
            game_close = True

        x1 += x1_change
        y1 += y1_change
        dis.fill(black)
        pygame.draw.rect(dis, green, [foodx, foody, snake_block, snake_block])
        pygame.draw.rect(dis, white, [x1, y1, snake_block, snake_block])
        pygame.display.update()

        if x1 == foodx and y1 == foody:
            print('Yummy!!')
        clock.tick(snake_speed)

    pygame.quit()
    quit()


gameLoop()

运行这段代码将会打开一个黑色的窗口，其中有一个白色的方块代表蛇，一个绿色的方块代表食物。您可以使用方向键控制蛇的移动。如果蛇撞到边界或自己，游戏将结束。如果蛇吃到食物，将会在控制台上输出'Yummy!!'。
