Importing related modules in Python

Question

I'm trying to import two "sub-modules" that are closely related, and I'm not sure how to import them in a way that shows that they are related. My file structure is as follows:

main.py
module/
    child_one/
        one.py
    child_two
        two.py

Is there a way to import one.py and two.py into main.py in a way that has them both as "submodules" of a parent, while shortening the name of the parent? For example something like this (which doesn't work, I think having . in the name is bad...):

import module.child_one as m.one
import module.child_two as m.two

I think if I didn't want to shorten the name of the parent, I could just import them as module.child_one and module.child_two without messing with their names.

Thanks!

Answer 1

from your module add __init__.py file

from that file import the two submodules

__init__.py

from child_one import one
from child_two import two

# or

from child_one.one import func_one
from child_two.two import func_two

you can use them by doing

import module

module.one.func_one()
module.two.func_two()

# or

module.func_one()
module.func_two()

Answer 2

class m:
    import module.child_one.one as one
    import module.child_two.two as two


t = m.one.func_one()
tt = m.two.func_two()

It works, but... unusial

Answer 3

You could import the whole module, give it an alias and then call each child.

import module as m

m.child1.foo()
m.child2.foo()

According to the accepted answer here whether you import the whole module or a single function does not make a difference unless you use the child modules in a loop.
