This video tutorial introduces object-oriented programming (OOP) in Python, emphasizing that everything revolves around objects. It explains that all classes, whether built-in or custom, inherit from the object class. The tutorial demonstrates using the IS subclass function to verify inheritance, first with the built-in int type and then with a custom Card class. The video concludes by reinforcing the concept that Python's OOP is centered around creating and manipulating objects.

What is the fundamental concept of Object Oriented Programming in Python?

• Everything is built around functions.

• Everything is built around objects.

• Everything is built around modules.

• Everything is built around variables.

What does the 'issubclass' function do in Python?

• It checks if a function is a subclass of another.

• It checks if a variable is a subclass of another.

• It checks if a class is a subclass of another.

• It checks if a module is a subclass of another.

Which built-in Python class is used as the base for all other classes?

• object

• str

• int

• list

What result do you get when checking if the 'int' class is a subclass of 'object'?

What is the outcome when checking the inheritance of a custom class from 'object'?
