Python PyCharm中的调试烧瓶

我试图弄清楚如何在使用Flask（Werkzeug）调试器调试Flask应用程序和使用PyCharm的调试器之间轻松切换。我已经有了两个PyCharm运行配置

我使用“Run”和提供给应用程序脚本的

--debug

标志调用的一个；及

我使用“Debug”和提供给应用程序脚本的

--pydebug

标志调用的一个

使用“我的应用程序脚本中支持的标志”

这是可行的，并且满足了我不需要编辑任何代码就可以部署到服务器的要求；但我不确定这是最好的方法。首先，我需要记住，第二个配置是使用“调试”（而不是“运行”）启动的，而第一个配置是使用PyCharm中的“运行”（而不是“调试”）启动的

---

是否有更好的方法支持PyCharm中的这两种调试方法，使用PyCharm的某些功能（例如，允许我检测何时调用了“调试”而不是“运行”），或者更智能地使用Flask的功能。

检查应用程序是否在PyCharm调试器下运行的一种非常简单的方法是：

'pydevd' in sys.modules

---

在Pycharm Professional 2020.1上，现在有了一个Flask服务器运行/调试配置选项，我可以使用以下输入（在断点处停止，分步执行，等等）

这适用于以下结构的项目：
