python - How to load all modules in a folder?

Question

Could someone provide me with a good way of importing a whole directory of modules?
I have a structure like this:

/Foo
    bar.py
    spam.py
    eggs.py

I tried just converting it to a package by adding __init__.py and doing from Foo import * but it didn't work the way I had hoped.

Answer 1

List all python (.py) files in the current folder and put them as __all__ variable in __init__.py

from os.path import dirname, basename, isfile, join
import glob
modules = glob.glob(join(dirname(__file__), "*.py"))
__all__ = [ basename(f)[:-3] for f in modules if isfile(f) and not f.endswith('__init__.py')]
