I'm getting an error that says cant compare songs to int's

Am i supposed to use int(self) instead of the length attribute in my comparison equations? Just wanted to make sure I'm at least thinking the right way

class Song:
    def __init__(self, artist, title, length):
        self.artist = artist
        self.title = title
        self.length = length
    def __int__(self):
        return self.length()    
    def __eq__(self, other):
        return self.length == other.length
    def __lt__(self, other):
        return self.length < other.length
    def __gt__(self,other):
        return self.length > other.length
    def __ge__(self, other):
        return self.length>= other.length
    def __le__(self, other):
        return self.length<= other.length
    def __ne__(self, other):
        return not self.length == other.length

In the int conversion, since "length" is a property and not a method, it should not be followed by parentheses.

Also, with the conversion installed, all the comparisons can be made just by converting "self" into an int and comparing it directly with the "other". For example:

    def __eq__(self, other):
        return int(self) == other
