Python Programming: Lesson 33 - Intro to Object-Oriented Programming

PLEASE SUBSCRIBE!!!

In the previous lesson (https://youtu.be/5ZzHTTyg3i0), we studied the generators supplied by the itertools modules, which are helpful functions for working with iterables. Here, we review the itertools module but then begin our exploration of object-oriented programming in Python, which should take us through most of the rest of the curriculum.

A class is a body of code that represents a data type that we're allowed to create. The data type can have fields that it accepts in a method called a constructor, which creates an instance of a class. A constructor usually assigns instance variables to values that the user passes in, such as name and age for an instance of a Person class.

A class usually also has instance methods, which can return or operate on a particular instance of a class. We provide an example of that in the second half of this video.
