注释（关于 [PyPI]: 无线电）：
因此，建议寻找替代方案：
最近遇到的一个是
Win32Wifi：（
[PyPI]：win32wifi，不过这个也没有更新自2017年以来）。更多细节请参见
[SO]：无法使用Python的WlanGetAvailableNetworkList获取所有可用网络(@CristiFati的答案)（还可以查看
[SO]：使用WlanScan在Python中强制进行wifi扫描(@CristiFati的答案)）。
，我成功找到了一些内容。

注释：
为了创建一个POC，我不得不添加一些代码（例如wireless_disconnect），这些代码并不一定与问题相关，但增加了复杂性。顺便说一句，代码比我最初预期的要复杂得多（这就是为什么我没费心去解释它——因为这会导致过度），但我看不到任何简化它的方法。
script00.bat（和time
正如我所指定的那样，这更像是一个POC，（我的和Win32Wifi的）代码存在一些限制。某些情况下（网络）可能需要进行（小）代码更改才能正常工作。
尽管连接到网络成功（并且有效），但在系统托盘中，网络状态仍显示为已断开连接（实际上在短暂的一秒钟内它会显示为已连接，但然后它会自动更改）。此外，系统托盘中的网络图标显示为已连接。我不确定这是我忘记以某种方式通知Win（虽然这没有太多意义），还是Win不喜欢“其他人”连接到无线网络。
最重要的一个：上述代码将无法直接使用，因为Win32Wifi存在缺陷。我发现了两个致命的（关键）错误，这对于这种情况来说是致命的，并且还有一堆其他较小的错误。我刚刚提交了kedos/win32wifi - Fixes（一些关键）和改进（已合并于200906年），但
PyPI上没有更新。
作为替代方案，您可以下载补丁并在本地应用更改。请参阅Run/Debug a Django application's UnitTests from the mouse right-click context menu in PyCharm Community Edition?（@CristiFati的答案）（Patching utrunner部分）以了解如何在Win上应用补丁（基本上，每行以一个“+”号开头的行都会进入，而每行以一个“-”号开头的行都会退出）。
winwifi.WinWiFi.connect('network_ssid', 'network_pwd')时，它无法重新连接。但是，如果我只做winwifi.WinWiFi.connect('network_ssid')-没有pwd- 它将重新连接到wifi。我有Python 3.8、Windows 10和PyCharm Community Edition 2020.2。 - xiaxio
