Martin Panter added the comment: This looks good enough to me. I would have probably avoided littering the page with too many Deprecated and Note boxes, but I can respect your and Berker’s preference to add the separate box. -- ___ Python tracker

Martin Panter added the comment: Not quite. This is a two-step deprecation: 1. “htmllib” is removed in favour of HTMLParser. The API is different, so no automatic 2to3 change would be practical. 2. HTMLParser is renamed to “html.parser”, and 2to3 handles this. This is already documented at

R. David Murray added the comment: The note should actually be parallel to the http one (assuming 2to3 does do the translation), rather than say "use instead", which would be incorrect advice for a python2 user :) -- nosy: +r.david.murray ___

Berker Peksag added the comment: Thanks for the patch. I think we can move the Python 3 part of the patch to a new note directive (similar to the example in httplib documentation: https://docs.python.org/2/library/httplib.html) For example: .. deprecated:: 2.6 Use :mode:`HTMLParser`

Martin Panter added the comment: PEP 3108 says “Superseded by HTMLParser”. I presume this means Python 3’s “html.parser” module (called “HTMLParser” in Python 2). I guess a lot of work would be involved in changing existing code over, but it shouldn’t be much of a problem for someone writing
