Re: python3 package import difference?

I believe you will need to track the modules in the folder  *dbi  *in the
root file '__init__.py'.

So there's an alternative to use the statement __all__ in the root filet
__init__.py, check the link where I find a use case:

*https://sentry.io/answers/what-is-init-py-for-in-python/#using-__init__py-to-run-code-and-control--imports
<https://sentry.io/answers/what-is-init-py-for-in-python/#using-__init__py-to-run-code-and-control--imports>*


References to take more deep in those issues:
PEP-3147 <https://peps.python.org/pep-3147/>
https://docs.python.org/3/tutorial/modules.html
<https://docs.python.org/3/tutorial/modules.html#intra-package-references>
     in this link above we have some examples of relative imports:
    from . import echo
    from .. import formats
    from ..filters import equalizer


In your code you're using "import *" , this is not a good practice when
using only some features in your module(s) because you'll inject more
garbage into memory if there are features you're not using.

Share with us the updates on your code.

I have an old library from 20 some years ago
for use with python2, that is structured like this:

     rcs
     ├── dbi

     │   └── regos.py
     └── __init__.py  --   *empty*

the __init__.py file under 'rcs' is empty.
The one under rcs.dbi contains:

     from dbi import *
     from regos import *

With python2, I'd go:

         import rcs.dbi

then I'd have access to stuff in regos.py
as:

When I do the same import with python3, I get:
