Issue
I have a directory structure as follows:
| main.py
| scripts
|--| __init__.py
| script1.py
| script2.py
| script3.py
From main.py
, the module scripts
is imported. I tried using pkgutils.walk_packages
in combination with __all__
, but using that, I can only import all the submodules directly under main
using from scripts import *
. I would like to get them all under scripts
. What would be the cleanest way to import all the submodules of scripts
so that I could access scripts.script1
from main
?
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 __init__.py
. I can use pkgutils.walk_packages
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 walk_packages
returns?) to import them.
Solution
Edit: Here's one way to recursively import everything at runtime...
(Contents of __init__.py
in top package directory)
import pkgutil
__all__ = []
for loader, module_name, is_pkg in pkgutil.walk_packages(__path__):
__all__.append(module_name)
_module = loader.find_module(module_name).load_module(module_name)
globals()[module_name] = _module
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 using globals()[module_name]
, 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/__init__.py
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.
