package import question

[Phoe6]

Hi all,
I have the following directory structure:

wallpaper/
-main.py
-ng/
-- __init__.py
-- setdesktop.py
-yb/
-- __init__.py
-- setdesktop.py

From main.py, I would like to do:

import ng
import yb
ng.setdesktop.run()
yb.setdesktop.run()

But it is not working! when I import the package, the modules present
inside the package are getting imported.

However, following the python document if I do
import ng.setdesktop
import yb.setdesktop

ng.setdesktop.run()
yb.setdesktop.run()
Works fine.

I would like to use the notation.
import <my_package_name>
and use the modules inside the package in the dotted module notation.
What should I do the enable such a kind of imports.

Please let me know.

Thank you.
Senthil

You need to import the setdesktop-module in the respective __init__.py-files
to make them part of the names known in there.

Put the line

from . import setdesktop

into both __init__.py files. Importing the package will then trigger the
submodule to be imported.

Thanks a lot for your replies. I had a thought that I can do this way,
but as Python Documentation did not mention it, I was 'thinking' that
submodules will automatically get imported and __init__.py usually
blank.

Thanks again,
