#class #constructor
In python every class has a constructor, but its not required to explicitly define it.

the __init__() method is a constructor and is always called when an object is created.

There are two types of constructors:
Default constructor - a simple constructor which doesn’t accept any arguments.

Parameterized constructor - a constructor with arguments.
