解决tkinter卡死问题
参考https://blog.csdn.net/qq_41204464/article/details/86707216
核心思路:
1.引入threading库
import threading2.在界面回调函数里面添加装饰器
# 打包进线程（耗时的操作）
@staticmethod
def thread_it(func, *args):
t = threading.Thread(target=func, args=args)
t.setDaemon(True) # 守护--就算主界面关闭，线程也会留守后台运行（不对!）
t.start() # 启动
# t.join() # 阻塞--会卡死界面！奉上本人写的基于tkinter做界面，然后百度关键字爬图程序。有日志调试，不卡死界面
#!/usr/bin/env python
#-*- coding:utf-8 -*-
import os, sys
import requests
import base64 #引入编码库
import threading #开线程
from time import sleep
if sys.version_info[0] == 2:
