二、分步详解
如果你是新手，请仔细看完这篇blog：Pygame教程（非常详细）-优快云博客
（1）设置背景及数字块资源
资源请自己准备，thank you
1.导入库
你需要这些库，so：
import tkinter
from tkinter import messagebox
import pygame
import sys
from pygame.locals import *2.初始化
你需要准备一个pygame环境，so：
pygame.init()
screen = pygame.display.set_mode((480, 320))
pygame.display.set_caption("计算器")
screen.fill((255, 255, 255))
action = []
a1 = pygame.image.load("宇宙背景图.png")
a2 = pygame.transform.scale(a1, (480, 320))
screen.blit(a1, (0, 0))3.填加数字块
你需要绘制出每个角色，so：
def draw(pictrue_name, x2, y2, blit_button):#定义一个绘图的函数
a1 = pygame.image.load(pictrue_name + ".png")
a2 = a1.get_rect()
a2.x = x2
a2.y = y2
screen.blit(a1, a2)
if blit_button == 'yes':
if pictrue_name.isdigit():
action.append([a2, int(pictrue_name), a1])#action这些列表可以暂时放一放，稍后再讲
else:
action.append([a2, pictrue_name, a1])剩下的只要不断用这个函数。
Tip：如果你又不知道的参数，如blit_botton，还是放一放。
段总结
import tkinter
from tkinter import messagebox
import pygame
import sys
from pygame.locals import *
wnd = tkinter.Tk()
wnd.withdraw()
def draw(pictrue_name, x2, y2, blit_button):
a1 = pygame.image.load(pictrue_name + ".png")
a2 = a1.get_rect()
a2.x = x2
a2.y = y2
screen.blit(a1, a2)
if blit_button == 'yes':
if pictrue_name.isdigit():
action.append([a2, int(pictrue_name), a1])
else:
action.append([a2, pictrue_name, a1])
pygame.init()
screen = pygame.display.set_mode((480, 320))
pygame.display.set_caption("计算器")
screen.fill((255, 255, 255))
action = []
a1 = pygame.image.load("宇宙背景图.png")
a2 = pygame.transform.scale(a1, (480, 320))
screen.blit(a1, (0, 0))
#......
（2）进入主循环
1.创建循环
很easy，来一个while，so：
while True:
2.加入亿点点python指令
也很easy，so：
while True:
for event in pygame.event.get():#检测事件
pygame.display.update()#更新
段总结
while True:
for event in pygame.event.get():#检测事件
pygame.display.update()#更新
（3）！！！重点来了！！！ ！！！检测事件中的代码！！！
请务必确认您准备好了，因为代码可能会有几百行长哦
请见上方代码👆
作者写代码时还不知道捕捉错误😑
请谅解这份十分复杂的代码吧！
请点个赞呗
马上结为您献上一份 捕捉错误的超短代码！
