module has no attribute

Question

I have a directory with a number of .py files in it. each file defines some classes. I also have an empty __init__.py in the directory.

Answer 1

You need an __init__.py in the myproject directory too. So your module structure should be:

myproject
    __init__.py
    mymodule
        __init__.py
        api.py
        models.py
        views.py

Answer 2

The problem is submodules are not automatically imported. You have to explicitly import the api module:

import myproject.mymodule.api
print myproject.mymodule.api.MyClass

If you really insist on api being available when importing myproject.mymodule you can put this in myproject/mymodule/__init__.py:

import myproject.mymodule.api

Then this will work as expected:

from myproject import mymodule

print mymodule.api.MyClass 

Answer 3

Modules don't work like that.

from myproject.mymodule import api
print api.MyClass

Answer 4

If you are an idiot, like me, then also check whether you didn't name your python file the same as the module you are trying to import.
