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):
        print('CLASS, methods:',               inspect.getmembers(o, inspect.isfunction))
    else:
        print('OBJECT ({}): {}'.format(
            o.__class__, 
            [(n, v) for n, v in inspect.getmembers(o) 
                if not n.startswith('__')]
        ))

2. Then, if we apply it to any object, we will get the details about its type, attributes, methods, and, if it's a function, its arguments. We can even make a custom type:

class MyClass: ...
