A class is a template for objects, and an object is an instance of a class.
When the individual objects are created, they inherit all the variables and methods from the class.

In python, we can create a class using the keyword class.
Method of class can be defined by keyword def. It is similar to a normal function but it is defined within a class and is a function of class. The first parameter in the definition of a method is always self and method is called without the parameter self.
__init__ Method
__init__ Method
__init__ is a method which is immediately and automatically called after an instance has been created. This name is fixed and it is not possible to chose another name. __init__ is one of the so-called magic methods,we will get to know it with some more details later. The __init__ method is used to initialize an instance. There is no explicit constructor or destructor method in Python, as they are known in C++ and Java. The __init__ method can be anywhere in a class definition, but it is usually the first method of a class, i.e. it follows right after the class header.a
