How to organize Python files in a (relatively) big project

[Claudio Grondi]

Maybe looking at the todays thread  ["dynamical" importing] can be helpful
also here.

some alternatives:

- if you want the modules to remain imported:

    try:
        sys.path.insert(0, os.path.join(module_dir, "bin"))
        module = __import__("my_module")
    finally:
        del sys.path[0]
    object = module.my_object

- if you're only interested in the object:

    namespace = {}
    execfile(os.path.join(module_dir, "bin", "my_module" + ".py"),
namespace)
    object = namespace["my_object"]
