Question

我正在使用Pycharm，我的Collection项目目录中有几个.py文件。

当我使用python控制台时，我可以导入我想要的任何类，模块（只要它存在）。但是过了一段时间后，目录变得有点乱，所以我尝试根据它们的共同点将它重新组织成子目录/文件。（如计算器子文件包含几个带计算程序的.py文件等。但是在处理那些嵌套文件时，我无法使用Python控制台 - 我无法导入任何自定义类：

我收到错误：ModuleNotFoundError

我相信这是因为sys.path.extend没有...扩展到那个非常的Calculator子目录。

我真的不希望将它们全部放在一个目录中，因为它会变得非常混乱。如何更改该特定子文件的路径？

您可能忘记在新创建的子文件夹中添加controller.gorder.XXXEndpoint recuperaDatiAgente: javax.jdo.JDODataStoreException: Communications link failure during commit(). Transaction resolution unknown.
