Inspection

Being a powerful dynamic language, Python allows us to change its runtime behavior based on the state of objects it's working with.

Inspecting the state of objects is the foundation of every dynamic language, and the standard library inspect module has most of the features needed for such a case.

How to do it...

For this recipe, the following steps are to be performed:

1. Based on the inspect module, we can quickly create a helper function that will tell us major object properties and type for most objects:

import inspect

def inspect_object(o):
    if inspect.isfunction(o) or inspect.ismethod(o):
        print('FUNCTION, arguments:', inspect.signature(o))
    elif inspect.isclass(o):
       ...
