How to correctly write a module?

Question

I have the following directory structure

RawRepo contains a simple class:

class RawRepo:
    pass

init.py contains:

__all__ = ["RawRepo"]

And yap-analysis.py, my "main file", uses either of the following, but it doesn't work:

from yap import RawRepo
from yap import *

when I try to instantiate it, saying:

TypeError: 'module' object is not callable

How to make it actually work? I want yap to be the module, and RawRepo just one of its classes.

Answer 1

Import the class in yap/init.py:

from .RawRepo import RawRepo

Then you can import it in yap-analysis.py like this:

from yap import RawRepo

Note that you can group multiple classes in on module. You should also consider to rename the module to something like raw_repo to conform to PEP8, "modules should have short, all-lowercase names."
