i think we could actually add the modules that @ucodery added here to this example. thus we have a simple add_numbers for teaching and a few other modules with dependencies for a more robust package setup.

Let's start with basic code and then we can make it more robust, add more tests etc later. even add a class - that might be good. (in a separate issue)

Are you wanting to make examplePy a dependency of this package? That won't work without some complex build setup as examplePy isn't a published project. Probably better to add pandas like you were originally thinking.
