__gt__() python

Question

Hello everyone,
i have a little problem with the __gt__() method.

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):
if Shape(self.width*self.height > other.width*other.height):
return True
else:
return False

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

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

print(result.area())
print(s1 > s2)

it returns "TypeError: __init__() missing 1 required positional argument: 'h'"
how can i fix it if i wanna know if the area of the s1 is bigger than the area of s2?
also, can i call somehow the "area()" function from above?
thanks for your help

Answer 1

To compare instance area to another you can simply do this ...

return self.area() > other.area()

Answer 2

yes you are right!
Thanks!

# Why you call the class in __gt__ ? You can do as follows:

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 self.width + other.width, self.height + other.height

def __gt__(self, other):
if self.width*self.height > other.width*other.height:
return True
else:
return False

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

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

print(result.area())
print(s1 > s2)
