Class made Simple. A real simple explanation of class in Objected Oriented Programming languages such as Python. This lecture will teach you all you need to know about crating/defining a class. You will understand what is a class in Object Oriented Language? How to create Instance of a class.

You will also learn about Class Level Variables versus Instance Level Variables. Difference between Class Level Variables and Instance Level Variables.

Class is a blue print that is used to create one or more instances of a class. Creating instances of a class allows, reusing elements of a class without the need for re-defining. You will learn techniques to reduce code redundancy. You will learn to develop leaner and simple code. More about this in the lecture.

You will also learn to create Line graphs, Bar charts and Pie charts using Python libraries. You will learn to add Titles. Legend, Labels, Grids and custom colors to your graphs.
