Before we delve deeper into classes and objects, let's first try to understand what they are and why they form part of Python programming. Python language also supports object-oriented programming. For beginners, this might be a little confusing topic but be assured it is not that difficult to understand the concept of object-oriented programming (OOP). Let's try to understand what object-oriented programming is. Before this concept was introduced, we were primarily slave to writing procedural programming, that is, going line by line. At this level, you need not understand what is procedural programming but certainly there is one example to illustrate it, that is, C language. In procedural programming, there were a lot of complexities and above all procedural programming had negligible code reuse concept.
