Frontend, Backend, where does Python fit?

In simple terms front-end is what you see; backend is how it works.

Front-end

The website is usually a mixture of HTML, CSS and Javascript, which are all controlled by the browser.

Constructors

A constructor is a function that initializes immediately as soon as the objects is created. See example below.

Update to Market Evaluation Program

An update to the Stock Market Evaluation Program that utilizes Classes and Objects to give some additional information in the form of Strings based on user inputs.

Classes and Self

Self is used as temporary placeholder for the object. See two examples below.

Object Oriented Programming

An object contains built in attributes. These attributes can be data and/or methods. Functions associated with an object are referred to as methods. 

Before an object can be created, a class must be created. A class is a blueprint for an object.
Many objects can refer to the same class.

See below for two examples of creating a class, and then creating an object.
