Rectangle area

I'm doing this in Pycharm and works but here it fails ....

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

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

Check your self.length in the area() property. Looks like you misspelled 'length'.
