class Rectangle: def init(self, width, height): self.width = width self.height = height def calculate_area(self): return self.width * self.heightWrite the definition of a class Square that:#1 inherits from the class Rectangle,#2 adds a method called calculate_perimeter that calculates and returns the square's perimeter#3 overrides the str method to print out the square's area and perimeter~.5 point for the class definition~.5 for method parameters ~1 point for the Inheritance ~1 point for the new method~1 point for the overrideclass Square(Rectangle): def calculate_perimeter(self): return self.width4 def repr(self): result = "Area=" + str(self.widthself.height) result += "Perimeter="+ str(self.width*4) return result
Solution
class Square(Rectangle): def calculate_perimeter(self): return self.width * 4
def __str__(self):
area = self.width * self.height
perimeter = self.width * 4
return "Area = " + str(area) + ", Perimeter = " + str(perimeter)
