How to load all modules in a folder?

Add the __all__ Variable to __init__.py containing:

__all__ = ["bar", "spam", "eggs"]

See also http://docs.python.org/tutorial/modules.html

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')]
