Python Question

How to import all submodules?

I have a directory structure as follows:

| scripts

, the module
is imported. I tried using
in combination with
, but using that, I can only import all the submodules directly under
from scripts import *
. I would like to get them all under
. What would be the cleanest way to import all the submodules of
so that I could access

EDIT: I am sorry that I was a bit vague. I would like to import the submodules on run-time without specifying them explicitly in
. I can use
to get the submodule names (unless someone knows of a better way), but I am not sure of the cleanest way to use these names (or maybe the ImpImporters that
returns?) to import them.


Edit: Here's one way to recursively import everything at runtime...

It uses exec, so there's almost certainly a better way, but it does work (even for arbitrarily nested sub-packages, I think).

(Contents of in top package directory)

import pkgutil

__all__ = []
for loader, module_name, is_pkg in  pkgutil.walk_packages(__path__):
    module = loader.find_module(module_name).load_module(module_name)
    exec('%s = module' % module_name)

I'm not using __import__(__path__+'.'+module_name) here, as it's difficult to properly recursively import packages using it. If you don't have nested sub-packages, and wanted to avoid the exec/eval, though, it's one way to do it.

There's probably a better way, but this is the best I can do, anyway.

Original Answer (For context, ignore othwerwise. I misunderstood the question initially):

What does your scripts/ look like? It should be something like:

import script1
import script2
import script3
__all__ = ['script1', 'script2', 'script3']

You could even do without defining __all__, but things (pydoc, if nothing else) will work more cleanly if you define it, even if it's just a list of what you imported.
