Re: Python __Underscore__ Methods
#2Like many similar articles, it seems to be missing the very important `next`. I understand it didn't actually gain underscores until Python 3, but it's still been part of one of the most important protocols in Python for many years (the iterator protocol).

#3The Python documentation is generally quite nice, but the article claims this information is missing or hard to find.
What would it take to get this information into the official python documentation and organized in an appropriate manner there?
There are so many tutorials and reference guides out there for any given language and they suffer from many deficiencies. They are often out of date, incorrect, unclear, or just plain wrong. But an article from 8 years ago has a good chance of being a top Google result. The minsinformation spreads. If the work was instead built into the official project documentation, it can be easily tracked and updated as the language/project evolves.

The only problem I've had with the official Python documentation is that it tends to segregate dunder methods by purpose: "how to impersonate a collection" documentation over here, "how to control instance creation" over there, "how to control method and attribute resolution" somewhere else. For intermediate-to-advanced Pythonistas it's good to have a rough idea of all the extension points Python offers, but the official docs already have a "_" page in the index, which lets you browse the list and click on interesting-looking names:

If you see the comments at the bottom, they highlight that the article is wrong on some of the instantiation-related magic methods.

Ja I was coming here to say this: the Python docs are really good on this, and why anyone would read or write something else is beyond me.

Sigh. I got bit by the same thing I was lamenting in my earlier post.
