46.Classes and Objects in Python- Accessors and mutators

Python is an object-oriented programming language, which means that it provides features that support object-oriented programming. The basic components of object oriented programming are  classes and objects. A Class is a blue print to create an object. It provides the definition of basic attributes(properties) and functions of objects. Object is a running instance of the class having the identity(name), properties( values) and behaviors(functions). The object oriented program thus consist of object definitions (classes) and most of the computations and functions are mentioned as operations on the object.Each object definition corresponds to some object or concept in the real world, and the functions that operate on these object correspond to the ways real-world objects interact. We have learned objects of string, list, tuple etc…and used the properties and functionalities of these objects which are built into the Python. Now we are going to create our own(user defined) objects. Th...
