Points to ponder
Instead of starting from the scratch, you can create class by deriving it from preexisting class by listing parent class in parentheses after new class name.
The child class inherits attributes of its parent class, and you can use those attributes if they were defined in child class.
Syntax:
The derived classes are declared much like their parent.
class SubClassName (ParentClasss1[, ParentClass2, ...]):
'Optional class documentation of string'
class_suitee
Example
Live Demo
Output:
Calling the child constructor
Calling the child method
Calling the parent method
Parent the attribute : 200
Similar way, you can drive class from multiple parent classes as follows:
class A: # define the your class A
class B: # define the your class B
class C(A, B): # subclass of the A and B
Don't miss out!
