Unexplained error in this code challenge

Hello,

I keep getting "Didn't get the right area" in this code challenge task 1.

rectangle.py
class Rectangle:
    area = 0

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

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

The entire property is indented too far, where it is now places it inside the other method.

Also, you can't create a "self.area" because it would conflict with the property itself. Use a different name, or make it a local variable, or just return the result of the calculation directly.
