In the file
cpython/blob/master/Lib/html/entities.py

the HTML5 named character references (line 264) do not look consistent.

Some references have a semicolon at the end, some not, and some have both variants.

Is there a reason for this?

Questions should usually be asked on python-list or elsewhere.

To answer, html5 was created from
https://html.spec.whatwg.org/multipage/named-characters.html
with these issues and patches.

The peculiarities in the dict keys reflect peculiarities in the standard. For instance, msg163706 of bpo-11113 says "the standard allows some charref to end without a ';', but not all of them."

I am leaving this open to add a link to the source file both in entities.py and the doc. It shows examples of the entities. A new one for me is smashp; U+02A33 ⨳.
