How do we implement abstract method in python? Give an example for the same.

Answer

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.side
