# Scientific Computing with Python Projects - Polygon Area Calculator

### Tell us what’s happening:

Do we no longer use replit? I have run the tests on the project description page and passed all but two. Unfortunately it doesn’t tell me what is wrong with my solution like replit did and so i don’t know what to change. Help would be appreciated.

you need to provide your code to get any help

Hi,

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

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

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

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

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

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

def get_diagonal(self):
return (self.width ** 2 + self.height ** 2) ** .5

def get_picture(self):
count = 0
string = '*'
line = string * self.width
result = f''
if self.width > 50:
return 'Too big for picture.'
elif self.height > 50:
return 'Too big for picture.'
else:
pass
while count < self.height:
if count == 0:
result = f'{line}'
else:
result = f'{result}\n{line}'
count += 1
return result

def get_amount_inside(self, shape):
x = self.width // shape.width
y = self.height // shape.height
return (x * y)

class Square(Rectangle):
def __init__(self, side):
self.side = side
self.width = self.side
self.height = self.side

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

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

def set_height(self, height):
self.set_side(height)

def set_width(self, width):
self.set_side(width)

I think it could be this

There should be a new line (`\n`) at the end of each line.

It keeps crashing when I test it, hopefully you have better luck
