# which methods of Python are used to determine the type of instance and inheritance?

Built-in functions in Python that work with inheritance: \

1- isinstance() – this method checks the type of instance.

eg. isinstance(myObj, int) – returns True only when myObj. class is int.

2-issubclass() – this method checks class inheritance

eg. ***issubclass(bool, int) – returns True because bool is a subclass of int.

***issubclass(unicode, str) – returns False because unicode is not a subclass of str.
