Slip 19 - B) Define a class named Shape and its subclass(Square/ Circle). The subclass has an init function which takes an argument (Length/radius). Both classes should have methods to calculate area and volume of a given shape.

 Solution :

class Shape:
pass class Square(Shape):
def __init__(self,l2):
self.l=l2
def SArea(self):
a=self.l * self.l
print("Area of Square:", a)
def SPerimeter(self):
p=4 * self.l
print("Perimeter of Square:",p) class Circle(Shape):
def __init__(self,r2):
self.r=r2
def CArea(self):
a=3.14 * self.r * self.r
print("Area of Circle:", a)
def SCircumference(self):
c=2 * 3.14 * self.r
print("Circumference of Circle:",c) #main body
l1=int(input("Enter Length of Square: "))
obj=Square(l1)
obj.SArea()
obj.SPerimeter() r1=int(input("Enter Radius of Circle: "))
obj=Circle(r1)
obj.CArea()
obj.SCircumference()

Output:
