Although I can applaud your creativity, this really is very hackish for
Python and definitely has a bad 'smell'.
Like you I work with many different languages, but I am not going to force
the natural flow of Python into something resembling Java or whatever
other language.
Simply doing:
Right now your code boils down to:
from VLMLegacy.VLM4997.Conditions import Conditions as VLM4997_Conditions
from VLMLegacy.VLMPC.Conditions import Conditions as VLMPC_Conditions
from VLMLegacy.WINGTL.Conditions import Conditions as WINGTL_Conditions
And while you are, of course, allowed to do so, it's not the way you would
want to approach it in Python.
For each subpackage/module you could add an import and __all__ to
__init__.py to expose Conditions and then shorten it all to:
import VLMLegacy.VLM4997 as VLM4997
import VLMLegacy.VLMPC as VLMPC
import VLMLegacy.WINGTL as WINGTL
So that you can do:
a = VLM4997.Conditions(rdr, 2)
a.test()
