I have a relatively small python program which is setup like this

Root--Network--DTOLots of py files which contain classes.Other py files in the project

Both in the Network and the DTO folder there is an empty __init__.py.

When I do from Network import DTO, import Network, Import Network.DTO I cannot use the module at all. The debugger says it's completely empty. The root contains the py file I am actually executing.

Both the the __init__.py files in the Network and DTO folder are compiled to pyc while all actual python files aren't.

Does anyone have any idea what I am doing wrong? I am using python 2.7

For that, you need to import the submodules in your __init__.py. It becomes more difficult to add an import for every submodule if you have many, as you do. In the case of many submodules (and in general), use __all__.

Here's an example for Root/Network/DTO/__init__.py:

__all__ = ['sample_module',...
]for module in __all__:__import__('DTO.%s' % module)

Now you can do from Network.DTO import sample_module. The same idea holds for your other modules, as well.
