OMG, this is super useful, thank you for the video.

I always thought that the class attributes must be defined in the __init__() method of the class, which I didn't always want to do, especially with classes of dozens of attributes, so I often used a single
dict() called "attributes" instead (like porsche.attributes["speed"] = 100) which was a bit easier to use but still a pain when using nested classes and having stuff like :D This is so much more clever, I wonder why beginner OOP tutorials don't mention it along with the most important concepts.

Great explanation! The big question in everyones mind is "Why would I use setattr instead of the dot syntax" :-)

Dear Mister Finxter, this was a beautiful delivered vid. Very clear. I would like to read a csv into class objects. The first line of the of the csv is row headers. How do i combine dict to_csv with setattr to have the row headers for the element names of the class? Do you have such an example?

Hey Chris, I notice you don't put 'object' in the class defintion, like class Mango(object): // is there a reason? Does it make a difference at all?
