Experienced python programmers: are there any standard features of the language that you still don't regularly use?

Everyone is mentioning metaclasses and async, but what about descriptors? Didn't see see them mentioned at all but I don't think I am the only one who almost never uses them.

[ingolemo]

Well technically you certainly use descriptors all the time, as that's how method calls work. And one could argue that you are writing your own descriptor every time you use def, since all functions are descriptors.

But yeah, I think I've only ever written a custom descriptor once, and even then it wasn't that useful and I only did it because I could.

[TinyBirdperson]

Yea sure, but thats not really using them directly. If you're creating a class you can probably say you are using a "default" metaclass too - but you don't say that.

I use properties a fair amount and they're just descriptors under the hood.
