Define a class that has a class method that references a class attribute when called. code example
Example 1: declare class python
# To create a simple class:
class Shape:
def __init__():
print("A new shape has been created!")
pass
def get_area(self):
pass
# To create a class that uses inheritance and polymorphism
# from another class:
class Rectangle(Shape):
def __init__(self, height, width): # The constructor
super.__init__()
self.height = height
self.width = width
def get_area(self):
return self.height * self.width
Example 2: class python
class A: # define your class A
.....
class B: # define your class B
.....
class C(A, B): # subclass of A and B
obj = C() #to create instance
# issubclass(sub, sup) boolean function returns true if the given
# subclass sub is indeed a subclass of the superclass sup
# isinstance(obj, Class) boolean function returns true if obj is an
# instance of class Class or is an instance of a subclass of Class
