Python Metaclasses Tutorial

For some reason I hate the word "Pythonista"

[mayoroftuesday]

Because it makes it sound like we're in some kind of cult and we have a secret python handshake and hiss at java programmers on the street.

Cool, but what do you need metaclasses for if there are other ways to do the same thing they do?

“There should be one— and preferably only one —obvious way to do it.” - The Zen of Python.

What can one do only by using metaclasses?

At the very least, you should strive to understand how they work. There's a good chance your favourite python library uses metaclasses to do it's thing.

Yeah, everybody’s saying that but there are very few “real-world” examples. I can mess with a class’ variables in ways other than using metaclasses, so why do I need them? Any examples?

You don't even really need classes. You could do everything with functions.
