not sure what I'm missing

I think I have it providing the length back as an int, and then I've put the comparisons in the class .. not sure what I'm missing

songs.py
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 int(self) eq int(other):

    def __ne__(self, other):
        return int(self) != int(other):

    def __gt__(self, other):
        return int(self) > int(other):

    def __lt__(self, other):
        return int(self) < int(other):

    def __ge__(self, other):
        return int(self) > int(other) or int(self) eq int(other) :

    def __le__(self, other):
        return int(self) < int(other) or int(self) eq int(other) :

Nice work! You have the right idea, there were some minor syntax errors in your code -- extraneous colons and replacing pseudocode operators with Python primitive operators. I cleaned it up the code and it passed for me.

Good luck with Python, it's a fun and useful language.

class Song:
    def __init__(self, artist, title, length):
        self.artist = artist
        self.title = title
        self.length = length

    def __int__(self):
        return int(self.length)

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

    def __ne__(self, other):
        return int(self) != int(other)

    def __gt__(self, other):
        return int(self) > int(other)

    def __lt__(self, other):
        return int(self) < int(other)

    def __ge__(self, other):
        return int(self) > int(other) or int(self) == int(other)

    def __le__(self, other):
        return int(self) < int(other) or int(self) == int(other)

Hi George,

Yes it's quite close. I'd say the main focus area is your int method, which needs the int() function:

    def __int__(self):
        return int(self.length)

Also, your use of eq returns a syntax error in my Python console. I'd use ==

Great job. I'm learning this stuff too, and it's not easy to remember, so I refer to the teacher's notes frequently.
