Answer 1

Classes are used to define programmatic objects. It is not merely about making code more readable, but also more extensible. For instance, if you define a class "person", that class can contain all the required variables to describe a person, such as name, age, height, weight. You can then inherit the "person" class in an "employee" class that adds information such as department, id_number. But you can also inherit the "person" class into a "customer" class that has info you need to track your customer and get in touch, such as email_address.

The class can also include methods that your program can use to interact with the objects. It'll all come up later in the course.
