Python Classes and Objects

General Introduction to Python Programming language:

Python is one of the easiest programming languages to either newbies or seasoned professionals alike. If you are completely new to a programming language, you should be able to pick up the concepts at a quicker pace and if you already have some coding knowledge (whatever might be the programming language that you have already learnt), learning Python is just a piece of cake.

If you’re here then we assume that you are very much interested in getting your hands dirty with the Python programming skills, so why delay? Let us deep dive into the basics of the programming language. The basics of any programming languages (C++ or Java etc) are the CLASSES and OBJECTS of the classes. The following section deals in great detail about these concepts, so let us get started.

Python Classes & Objects:

In general object-oriented programming notation, a class is a container of your data and the methods that perform actions on these data. In other words, a class is the one that bundles your data and the functionality together as a single unit. Once a class is created, you create instances of the class for your programmatic usage which are then termed as objects. You could understand the class to be equivalent to a template with empty placeholders and objects to be photocopies of the template but the only difference is that each photocopy has its own related details added to it, than that are available on the class itself.

As already mentioned above that Python is an object-oriented programming language, the main focus remains on classes and objects rather than on functions as present in any procedure oriented programming language. A class can be defined in Python programming language using the class keyword. A class that we create using Python should always have a docstring (a string to define and describe what the class is for?), not mandatory but it is good to have one.
