Is it possible to strictly run plugin from self contained subdirectory?

Im new to python scripting and im learning to create a plugin for Painter but I would like to run a plugin from a self contained subdirectory from within the Painter python plugin directory. I dont want to have a script file run from that plugin directory but rather my plugin subdirectory. Ex.

Not

python/plugins/myPlugin.py

Yes

pytho/plugins/myPlugin/myPlugin.py

Is this possible?
