1) Does the 'Art' directory under C:/some_Directory contain a "__init__.py"
file?
2) Does the 'Scripts' directory under 'Art' contain a "__init__.py" file?
3) Is a file called 'myModule.py' located within the 'Scripts' directory?
If all of that is true, then you should be able to use the
'Art.Scripts.myModule' import path via the __import__() function

This particular approach is just a lower level way of using the
__import__() function. It also requires the use of your PYTHONPATH to find
the module, or a path you provide. If you look at the docs for that
function it says you cannot pass a dot-named module. It needs to be the
actual module you want, and optionally a path to search for it. I don't
think this is what you want, since the suggestion was to either use the
__import__ approach if you want to use your PYTHONPATH and a standard
import path ("a.b.c"), or to use imp to load an absolute file path.

This should be using the absolute path. Not a relative path.
fp = os.path.join(os.environ['MAYA_TOOLS_REPO'], 'Art/Scripts/%s.py' %
moduleName)
module = imp.load_source("myModuleName", fp)
