+1.Class is a datatype and implementation.
+
+2.A variable of class type is called object.
+
+3.An object of a class type is used to access methods and variables of the class.
+
+4.Syntax:
+   class class_name:
+                     #list of methods and attributes
+
+5.A method is procedure associated with an object and a message.
+
+6.self keyword is used to identify between two different objects of the same class.
+
+7.The method __init__() is called initializer and it is called implicitly whenever an object of the class is 
+created. It is customized to a specific initial value.
+
+8.When a derived class inherits from a base class, the methods and attributes from the base class is now available in derived class.
+Hence we need not type the same code to do the same job.
