Say I have this package layout
\myPackage
__init__.py
moduleA.py
moduleB.py
Is there a way (and I'm sure there is...) to query, for a given package
level, which modules live under it?
I thought I could do it like so:
import myPackage
goodQualityInfo = dir(myPackage)
One way to do this is to include an __all__ attribute in __init__.p]:
__all__ = ['moduleA', 'moduleB']
Then instead of dir(myPackage) use myPackage.__all__.
The name is standard though it is usually used for a slightly different
purpose:

Thanks. I was considering that too, but I want to be able to have people
drop modules in that dir and "be done with it": Not also have them also
need to update __all__ in __init__.py
Appreciate the suggestion though.
My current hacky plan is just query the location on disk of the imported
package, then do a dir search for .py files in that dir, and process those.
Seems clunky though.
Doesn't seem clunky to me. And if you do it in __init__.py, you can use
the __file__ attribute to get your base directory. Just put the results
in __all__ and you combine both ideas.
