I'm surprised that no one has yet mentioned packages.
Suppose you have the following folder layout and you stick an empty
__init__.py in each subfolder, like so:
app/
tools/
__init__.py
open.py
close.py
extensions/
__init__.py
inner.py
outer.py
Scripts in the 'app' folder can then import from the subfolders using
dotted notation:
import tools
from tools import open, close
import tools.extensions
from tools.extensions import inner, outer
However, with empty __init__ files, you can't use attribute lookup on
nested modules, so if you started with an 'import tools' any attempts
to reference the contents of the module in the following ways will
fail:
tools.open
tools.close
tools.ext.inner
tools.ext.outer
To provide this functionality, you need to import the items you want
available in the __init__ of the package they belong to. So by adding
the following:
tools/__init__.py: import open, close, ext
tools/ext/__init__.py: import inner, outer
You can then do a single 'import tools' and use standard attribute
lookup to access the contents of your subfolders.
