Course Description
Object-oriented programming (OOP) is a powerful programming paradigm that reduces the complexity of systems as is employs heavy re-usability of code. OOP leverages the concept of objects and classes. Objects may contain data (known as attributes, stored as instance or class variables) as well as procedures (defined as methods). Objects are generated from blueprints known as classes, which specify the attributes and methods to be generated at the time of object instantiation. This course introduces the internals of classes and the utilization of objects, as well as important object-oriented programming fundamentals such as inheritance, polymorphism, and composition.

Getting ready for object-oriented programming
FreeIn this chapter we quickly review functions and data structures, as they are building blocks of object-oriented programming. Then we transition into the conceptual definition of objects and classes.
-
Fancy classes, fancy objects
We create fancier classes with sophisticated methods such as importing datasets, getting descriptive statistics, and renaming columns. Also, we cover best practices for creating and documenting classes according to PEP-8.
-
Deep dive into classes and objects
Here, we dive deep into the internals of classes, instantiation of objects, the initialization method, instance variables, class variables, overriding class variables, and methods.
-
Inheritance, polymorphism and composition
In this chapter we cover inheritance, which is when we create a class that employs (or 'inherits') all class variables and methods from a 'parent' class. We also cover polymorphism, which is when multiple classes inherit from a single class. Finally, we cover composition, which is when classes employ specific class functionality from other classes without necessarily inheriting from them.
