There are lots of examples to crib from. Looking at those is how I learned how to use PLY:
This is a very very simple example, but is an end to end PLY lexer and parser. No matter how big your system gets it still looks like this: http://www.dalkescientific.com/writings/NBN/parsing_with_ply.html . It's an almost trivial example, but you can probably see how you would extend the singular "Atom" into different statement objects that you would define. These statement objects then would call your python class with the parameters. Or if you don't need to parse separately from the execution, you could just make your calls inside p_*. Definitely take a look at the examples in the source repo: https://github.com/dabeaz/ply/tree/master/example . They range from simple to extremely advanced, but they don't take very long to read over. That should get you where you need to go.
