I don't see what's wrong

Not sure what's wrong here, I'm looking back and fourth on the video, and the code from last video, but I guess it's not as simple as I want it to be? Please help

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


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

You're pretty close, but instead of the property name, the decorator should just be the word "@property".

And in the definition itself, the property name doesn't need to be enclosed in double underscores. That's the convention for "magic" methods that are generally not invoked directly, such as __init__ there.

Tried to do it again, but it still says try again.

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


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

That looks correct. :+1: Check the indentation in case it has mixed tabs and spaces, that's one possible problem that wouldn't show up here.

If that's not it, try restarting your browser.
