Like any other types of objects, you can use the "dir()" to list its members:
>>> def x(): ... print("Hello world!") ... >>> dir(x) ['__annotations__', '__call__', '__class__', '__closure__', '__code__', '__defau lts__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__get__', '__getattribute__', '__globals__', '__gt__', '__hash__', ' __init__', '__init_subclass__', '__kwdefaults__', '__le__', '__lt__', '__module_ _', 'Python Tutorials', '__ne__', '__new__', '__qualname__', '__reduce__', '__reduce_ex_ _', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']
You can call (execute) the function object by call its "__call__()" function:
>>> def x(): ... print("Hello world!") ... >>> x.__call__() Hello world!
⇒ '__dict__' Dictionary in Function Object
