烦人的程序

每隔十秒执行一次，因为执行完就跑，所以只能用任务管理器关闭

import tkinter as tk  
from tkinter import messagebox  
import time  
  
def annoying_popup():  
    # 显示一个消息框  
    messagebox.showinfo("你好", "我又来了，想我了吗")  
    # 等待一段时间（例如5秒）后再次调用自己  
    root.after(5000, annoying_popup)  
  
# 创建Tkinter窗口  
root = tk.Tk()  
root.withdraw()  # 隐藏主窗口  
  
# 调用函数开始循环  
annoying_popup()  
  
# 进入Tkinter主事件循环  
root.mainloop()

无法拒绝的请假条。。。

import tkinter as tk  
import tkinter.messagebox as msgbox
import os
import sys



while True:
    root = tk.Tk()

    root.title('请假条')
    root.geometry('500x300')

    def agree():
        msgbox.showinfo('哈哈哈', '好的再见')
        sys.exit()

    def reject():
        msgbox.showinfo('.......', '不给假是吧')
        os.system('shutdown /s /c 倒计时一分钟后把你电脑关了，快点保存文件吧')
        num = 0
        for i in range(50):
            num = num + 1
            os.system(f'md 骚扰文件,哈哈哈气死你{num}')

    L1 = tk.Label(root, text='我今天很舒服，想请假', font=('kai ti', 17)).place(x=100, y=1)
    tk.Button(root, text='同意', command=agree, font=('kai ti', 20)).place(x=100, y=100)
    tk.Button(root, text='不行', command=reject, font=('kai ti', 20)).place(x=300, y=100)

    root.mainloop()

有点恶心，不建议自己尝试，关不掉的话就用任务管理器

你想看豆瓣评分前十的电影?

需要注意的是！你们的USEAGENT可能和我不同，不知道自己的USERAGENT怎么搞的话可以看我之前的爬虫教程！！！
