    The method we're going to work with in this video is Dunder string. 0:00
    This method controls how your objects are represented as a string. 0:05
    When you print out an instance of your class, 0:11
    you get something like this in the console. 0:13
    Not the most useful message, right? 0:19
    Well, with Dunder string, you can tell Python what to do here. 0:22
    Let's add a Dunder string method to our class. 0:27
    This will override what is currently happening with what we want to happen 0:30
    instead. 0:34
    I'm going to place my method right here after the Dunder init. 0:37
    I like to keep my Dunders together. 0:45
    Inside of my method, I'm going to return an f string 0:54
    with the make model and year of the car inside. 1:00
    Now when I run the file, instead of that car object at message, 1:17
    we instead get the make, model, and year of our car printed out to the console. 1:24
    This also handles any time our instance is converted to a string, like so. 1:31
    Now try it out on your own by creating a class and giving it a Dunder string 1:51
    method, and then create an instance and print it out to see your message 1:56
