实际上,一个包通常对应一个包含python文件和其他目录的文件目录。要自己创建python包,请在其中创建一个目录和一个名为__init__.py的文件。在这个文件中包含被视为模块时的包内容,或者它可以留空。 注意:没有__init__.py文件的目录仍然被python看作是包。但是,不是作为常规包,而是称为namespace packages。 通...

For Python packages that have a module structure more than two levels deep, the graph can easily become overwhelmingly complex. Use the--max-module-depth=nflag to examine the internal dependencies of a package while limiting the module depth (private and testing-related modules are removed to fu...
