The NotImplemented docs aren't explicit enough when it comes to where it can/should be used. Patch attached.

It would be nice to also clarify and differentiate NotImplementedError as well.

Added further notes to `NotImplemented` and `NotImplementedError` to clearly state the differences between the two. I also added some more details to `TypeError` - I'm amazed at how little was described for such a common exception!

Maybe I explained a bit too thoroughly in some parts, but I like to have everything unambigous and well explained.

I haven't yet spent the time to learn how to build documentation (Soon™), so I'm going off the existing docs, and I try to follow the style as closely as possible.

New patch with small tweaks. Thanks Jelle for the comments!

More tweaks after Ethan's comments. This is starting to get way outside of the realm of NotImplemented, but it still makes for a good reference to point confused users at.

Emanuel, have you seen <>? From my experience, install Sphinx, and then “make -C Doc/ html”.

About the patch, I think the “.. note” boxes should be intended under the NotImplementedError heading. The current box looks wrong sandwiched between NotImplemnted and Ellipsis.

(Personally I think “Note” boxes are an annoying distraction anyway, and should normally be written into the surrounding text. In this case “Note that” inside a “Note” box seems doubly redundant. But other people seem to like them, so I try to resist complaining :)

Martin: yes, I plan to install Sphinx soon enough, so that I can build the docs.

As for the notes part, I indented it exactly like it was indented for other existing notes boxes in the same file. I'll change that if needed though.

I think the box about NotImplementedError needs indenting too. See the box for <> for a better example.

New patch with proper indenting, should be good as far as formatting is concerned :)

Obligatory monthly ping.

Did a little rewording and trimming (and formatting).  Tried to keep the ideas while not being so verbose.

Thanks Ethan for the improved patch! Pointed out a typo and some nits, but other than that it's mostly good. I'm not that good at brevity, and I think your patch is much better on that regard :)
msg271833 - (view) Author: Ethan Furman (ethan.furman) * (Python committer) Date: 2016-08-02 17:19
Fixed the typos (thanks!), removed the self-reference, and went with "similar names and purposes".
