Python Object-Oriented Python Dice Roller Compare and Contrast

alittle bit confused

just out of curiosity I feel like I am missing something. I feel like I should be adding other instead of song as one of the attributes. but if thats the case then why? as well as for seconds.

songs.py
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, Song):
        return int(self) == seconds 

    def __gt__(self, Song):
        return int(self) > seconds

    def __lt__(self, Song):
        return int(self) < seconds

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

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

You haven't defined anything named "seconds", so you can't compare to that.

And it's certainly more conventional to name the second argument "other", but not technically necessary. Just compare to your second argument. But notice that sometimes you spelled it with a capital "S", and other times with little "s" — that's OK too, just make sure the reference matches the argument in each method.

And you can simplify the last comparisons by using different operators (just one for each): "<=" for "le" and ">=" for "ge".
