Description
在day12作业中遇到了这样的问题：
代码正确的被执行了，但是不弹出二维码。（并且同样的代码在mac系统下能正常运行并弹出登录二维码）
这是运行后的截图（只运行，不出结果）：
一开始我的代码是这样的:
后来我加上了
if name=='main':
main()
这个语句，问题就解决了。
如下图：
本来
if name=='main':
语句是用来定义在用import引用它的时候，不执行语句后的命令，但是这里却能够用来帮助windows系统更好的判断代码应该执行哪一部份。帮助我解决了问题。
希望能帮助到遇到同样问题的同学。

Research direction
Start from the day12 assignment entry point and reproduce the QR-code behavior on Windows, comparing it with macOS. Check how execution changes when the if __name__ == '__main__': main() guard is added; done would mean confirming the cause and recording the workaround clearly for other learners.
