What are extensible Python application architectures (OOP)?

Question

Python

What I was going for, here is the directory:

- - cgi-bin
- - | - - a.py
- - | - - a
- - | - - | - - __init__.py
- - | - - | - - b.py
- - | - - | - - b
- - | - - | - - | - - __init__.py
- - | - - | - - | - - c.py
- - | - - | - - | - - c
. . .

It would be convenient for me to access access to child classes in the same way as a property call.
That is, the class "a" in the file "a.py" -

class a:
  prop = 5

and in another package called "a", in file "b.py" class "b"

class b (a):
  prop = 7

after import, it would be convenient to refer to the class and its property like this:

a.prop
a.b.prop
# 5
# 7

Expandable? Yes.
But since the import looks for the package first, I can't load the "b" module.
If there is something more convenient and extensible, please provide an example.
And if my version has the right direction, then how to make it work?
Thank you!

just crying! pearl :)

Answer 2

some kind of fluff.
what will be imported, module a or package a? how does the interpreter know what you want from it?
