Re: is this a good way to do imports ?

hello,

I can't find any good documentation or examples of packages,
so I'm not sure if this is good / correct way, although it seems to work.

root
/ dir1
/ file1.py
/ general.py

/ dir2
/ file2.py

/ general_root.py

Now I want to be able to use functions of file2 in file1,
and vice-versa.
In practice the directory structure is more complex and nested more deeply,
and basically I want all modules to be reachable by all other modules.

One straightforward way is plain old absolute imports. Assume root is
in the import path (for instance, in site packages)

>
==== file1.py ====
import general

from root.dir1 import general

import file2

from root.dir2 import file2
or even
from root.dir2.file2 import func
This will break if the tree changes. So will new relative imports.
Pulling everything into root in its __init__.py breaks if there are
duplicate module names.

Anyway, above is what I am doing with my current 3-level
(pac.subpac.mod) package until I learn something really better, given
that the interdependencies in my package should remain relatively sparse.
