Python贪吃蛇简单的代码
在⾃学Python的过程中在⽹上查询资料时发现了⼀些好玩的东西，python的游戏库模块，它可以⾃⼰弄⼀个⼩游戏来玩玩，然后我在⽹上了⼀些游戏的代码，，⾃⼰改了⼀些，弄出了⼀个简单贪吃蛇，代码也是照着敲的只是稍微的改了⼀下
import pygame, sys, random, time
from pygame.locals import *  # 从pygame模块导⼊常⽤的函数和常量
#定义颜⾊变量
black_colour = pygame.Color(28, 56, 20)
white_colour = pygame.Color(255, 144, 20)
red_colour = pygame.Color(255,34 , 20)
grey_colour = pygame.Color(150, 150, 150)
#定义游戏结束函数
def GameOver(gamesurface):
# 设置提⽰字体的格式
GameOver_font = pygame.font.SysFont("MicrosoftYaHei", 16)
# 设置提⽰字体的颜⾊
GameOver_colour = der('GameOver', True, grey_colour)#只能英⽂
# 设置提⽰位置
GameOver_location = _rect()
GameOver_location.midtop = (310, 200)
# 绑定以上设置到句柄
gamesurface.blit(GameOver_colour, GameOver_location)
# 提⽰运⾏信息
pygame.display.flip()
# 休眠5秒
time.sleep(5)
