Calendar fails to produce html on year and month

[pgdr]

Bug report

Bug description:

Calling

python -m calendar -t html 2025 10

results in the message error: incorrect number of arguments.

However, according to the arguments, it should be supported:

calendar.py [-h] [-w WIDTH] [-l LINES] [-s SPACING] [-m MONTHS] [-c CSS] [-L LOCALE] [-e ENCODING] [-t {text,html}] [-f FIRST_WEEKDAY] [year] [month]

I have attached a patch, and if there's support for it, I can create a PR for it.

0001-Add-calendar-year-month-support-for-html.patch

CPython versions tested on:

3.12, 3.13, 3.14

Operating systems tested on:

Linux

I just found the change that brings about this behavior: 8b7bc06

The more original change: 49fd7fa#diff-7976dc087a43c5bd465c0df88ff25bca03e469ea5d17478d81fd17472df87c28R678

It has been like this for many versions, so I think this is a feature.

Hi! I’m not 100% sure right now (and I don’t have access to my laptop this week), but I think I considered adding this feature when I was working on that test coverage. In the end, I came across a very old thread (maybe a patch review?) where @rhettinger was opposed to changing the module’s interface and/or output — and his arguments were very solid. Maybe Raymond can quickly weigh in on this..

@bxsx @rhettinger If this fix is not wanted, I think we should at fix the error message error: incorrect number of arguments.

It would be better to say something like error: HTML formatting does not support year-month option.

The PR #140230 is in any case ready to be reviewed.
