Re: import and package confusion

I am going around in circles right now and have to
admit I do not understand what is going on with
import of hierarchical packages/modules. Perhaps someone

can get me on the road again. Here is a subset of what I am trying to accomplish:

The package directory set up:

        VLMLegacy/
          __init__.py
          Reader.py
          Conditions.py
          VLM4997/
            __init__.py
            Conditions.py
          WINGTL/
            __init__.py
            Conditions.py

The inheritance:
        object
          Reader
            Conditions
              VLM4997.Conditions
              WINGTL.Conditions

Now how do I use import or from to be able to use these modules? The following is not 'real'

code and is only intended to give some idea of
what I am trying to accomplish:

import sys
sys.path.extend (['../lib', '../bin'])

import VLMLegacy.VLM4997.Conditions
import VLMLegacy.WINGTL.Conditions

Each of these imports a module in a subpackage in a package.

b = VLM4997.Conditions(2)

I see some confusion here.
(1) This should give a NameError('VLM4997')
(2) Even if changed to b = VLMLegacy.VLM4997.Conditions(2),
    You are calling an imported module, rather than a function or class.

So, using my crystal ball (which came back from the shop covered
in some sticky fluid), I guess you might mean:
    import VLMLegacy.VLM4997.Conditions.Conditions as VLM4997_Conditions
    import VLMLegacy.WINGTL.Conditions.Conditions as WINGTL_Conditions
    ...
    b = VLM4997_Conditions(2)
    b.test()
    ...
