Python: importing all modules from a specified py filepath

thePyFilePath= "D:\\Test.py";

#Python 2.x

import imp;

allModules= imp.load_source("__all__", thePyFilePath);

#Python 3.x

from importlib.machinery import SourceFileLoader;

SourceFileLoader("__all__",pyFilePath).load_module();

In Maya, both create a pyc file.

2.x creates a pyc file in the same folder as the py file.

3.x creates a pyc file in the __pycache__ folder.
