我正在看“ Learn Python The Hard Way ”教程，当它告诉我在安装后在 Powershell 中键入 Python 来尝试它时，它一直给我这个：
PS C:\Users\Zach> python
Traceback (most recent call last):

from _sre import MAXREPEAT
ImportError: cannot import name MAXREPEAT
我也尝试通过命令提示符运行并得到相同的错误。我已经安装和卸载了大约 3 次 python，并且重新启动了几次无济于事。我对python很陌生，我对在这里做什么感到困惑。我也很感激任何指向其他 python 教程的链接。
