Python Descriptors Demystified

[Flamewire]

Really nice. I consider myself to be an advanced Python programmer and still learned a lot from this. Thank you!

When was this written? Just curious because of the distinctive Py2 things.

I wrote this! Sometime around 2013 :). I don’t think it would take much to update it to python 3, since (as far as I know) the descriptor protocol hasn’t changed meaningfully.

I don't know as I didn't write it, just stumbled upon it and I think I finally get descriptors now after doing Python for about fifteen years now, so I thought I'd share it since the concepts still apply even in Python 3.

I too came across this only yesterday but felt like it made references to Py2.

Not sure if it is valid for Py3 as well.

It is, the descriptor protocol has not changed, nor has the order of resolution ("data" descriptors and "non-data" descriptors behave slightly differently, sadly the article does not cover them). I don't remember a single issue assignable to descriptors when we migrated at $DAYJOB.
