We'd like to compare songs by their length,

We'd like to compare songs by their length, which is measured in whole seconds. Create an int method that should return the length of the song. Then, create the following comparison methods: eq, lt, gt, le and ge.

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

This code challenge is testing what you learned in the previous video.

You'll be creating the methods that when called will perform various calculations using comparison operators

Remember how you define methods in Python.

def __int__(self):
     return ...

You define a method, give the method a name and then use self as a default argument.

You then perform the calculations by returning the result.

Use the other methods to return the result of the _int method and return calculations on them. Revew the video if you're still struggling. :)
