python3.8做贪吃蛇

Python 3.8是一种流行的编程语言，可以用来开发各种类型的应用程序，包括游戏。下面是一个简单的Python 3.8贪吃蛇游戏的示例：

import pygame
import random

# 初始化游戏
pygame.init()

# 定义颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
RED = (255, 0, 0)
GREEN = (0, 255, 0)

# 设置屏幕尺寸
screen_width = 800
screen_height = 600
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("贪吃蛇游戏")

# 定义蛇的初始位置和大小
snake_block_size = 20
snake_speed = 15
font_style = pygame.font.SysFont(None, 50)
score_font = pygame.font.SysFont(None, 35)


def our_snake(snake_block_size, snake_list):
    for x in snake_list:
        pygame.draw.rect(screen, GREEN, [x[0], x[1], snake_block_size, snake_block_size])


def message(msg, color):
    mesg = font_style.render(msg, True, color)
    screen.blit(mesg, [screen_width / 6, screen_height / 3])


def game_loop():
    game_over = False
    game_close = False

    # 初始化蛇的位置和移动方向
    x1 = screen_width / 2
    y1 = screen_height / 2
    x1_change = 0
    y1_change = 0

    # 初始化蛇的长度和身体坐标列表
    snake_list = []
    length_of_snake = 1

    # 初始化食物的位置

        clock = pygame.time.Clock()
        clock.tick(snake_speed)

    pygame.quit()


game_loop()
