Tell us what’s happening:

Please help me rectify my code as i am constantly stuck on the 15th test

Your code so far

class Rectangle:
    def __init__(self, w, h):
        self.width = w
        self.height = h

    def __str__(self):
        return f'Rectangle(width={self.width}, height={self.height})'

    def set_width(self, w):
        self.width = w

    def set_height(self, h):
        self.height = h

    def get_area(self):
        return self.width * self.height

    def get_perimeter(self):
        return 2 * (self.width + self.height)

    def get_diagonal(self):
        return (self.width ** 2 + self.height ** 2) ** 0.5

    def get_picture(self):
        if self.width > 50 or self.height > 50:
            return 'Too big for picture.'

        pic = '*' * self.width + '\n'
        pic = pic * self.height
        return pic

    def get_amount_inside(self, ob):
        return self.get_area() // ob.get_area()


class Square(Rectangle):
    def __init__(self, s):
        super().__init__(s, s)

    def __str__(self):
        return f'Square(side={self.width})'

    def set_side(self, s):
        self.width = s
        self.height = s

Take a look what’s printed by this example, and whether that makes sense:

s = Square(5)
print(s)
s.set_height(6)
print(s)
s.set_width(15)
print(s)
3

Square(side=5)
Square(side=5)
Square(side=15)

This what it is printing
I think it makes sense

4

Why changing the width changes what is printed, but changing height doesn’t? Remember this is the square, where width is technically the height and they shouldn’t be different.

5

But i have assigned them both ‘s’(side) in square
So what should I improve

6

That’s just when new Square instance is created, isn’t it?

7

Yes , but that is what is required right?
Else how I am supposed to calculate for the square

8

Consider again the example:

  • Square is created with side 5
  • Height is changed to 6, but square still appear as having side 5.
  • Width is changed to 15, square now appears as having side 15.

Problem is not when square is created, but when attempt to change is made.

9

So what should I change in my code?

10

can you find where the behaviour comes from on your own?
