Shape Factory - Intermediate Python

Question

I’m having some trouble with this Code Coach. How do I fix the code?

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

def area(self):
return self.width*self.height
def add(self,other):
return Shape(self.width+other.width,self.height+other.height)
def gt(self,other):
return self.area()>other.area()

w1 = int(input())
h1 = int(input())
w2 = int(input())
h2 = int(input())

s1 = Shape(w1, h1)
s2 = Shape(w2, h2)
result = s1 + s2

Answer 1

The dunder for adding up was supposedly __add__( ... ) you have written it add( ... ) - you missed the underscores.

Also, if the task asked you to print something out, you should. I don't see your code printing anything. I thought the task requires you to print area of the <result> object

Answer 2

I added the underscores but didn’t need to print anything out for it to pass the test cases. Thank you very much :)
