Why am I getting an error ?

I don't why my code is not passing

rectangle.py 
class Rectangle:
    def __init__(self, width, length):
        self.width = width
        self.length = length

    @property    
    def area(self):
        value = Rectangle(width * length)
        return self.(value)

Hi Matthew. Please what are you trying to do exactly? if it is to create a method in the form of an attribute which calculates the area, then it's simply:

@property    
def area(self):
    return self.width * self.length

If it is to solve the challenge in the course then:

def __init__(self, width, length):
    self.width = width
    self.length = length
    self.area = length*width

should be enough.

Hello, you need just to add the area property to the class not creating a new function, so you just need to add self.area = self.width * self.length to the existing class, Rectangle.
