Short Answer TypeHow do we implement abstract method in python? Give an example for the same.
Abstract method: An unimplemented method is called an abstract method. When an abstract method is declared in a base class, the derived class has to either define the method or raise 'NotImplementedError'.
class Shape(object):
def findArea(self):
pass
class Square(Shape):
def __init__(self,side):
self.side = side
def findArea(self):
return self.side * self.sideWhat will be the status of the following list after the First, Second and Third pass of the insertion sort method used for arranging the following elements in descending order?
22, 24, 64,
34, 80, 43
Note: Show the status of all the elements after each pass very clearly underlining the changes.
