An OO program is structured as$$

Question $10$ options:

Everything is an Object.$$

Computation is performed by objects communicating with each other by messages, requesting that other objects perform actions.$$

Each object has its own memory, which consists of other objects.$$

Every object is an instance of a class. A class simply represents a grouping of similar objects, such as integers or lists. $$

The class is the repository for behavior associated with an object. $$That is$,$ all objects that are instances of the same class can perform the same actions.$$

Classes are organized into a singly rooted tree structure, call the inheritance hierarchy. $$Memory and behavior associated with instances of a class are automatically available to any class associated with a descendant in this tree structure.$$

Python is an OO programming language.
