Offer Python Latest (nightly master trunk build)

[cooperlees]

One of the features I love most about TravisCI is the ability to build my projects CI with top of Trunk Python (master branch). This allows me to know about deprecations etc. coming very early and have time to work on the fixes sooner.

Can actions look at supporting building a Trunk version nightly? Here is an example usage with Travis: https://github.com/facebookincubator/ptr/blob/master/.travis.yml#L16

Haven't dug in deep, but would also love to have the ability for this build to be able to fail and not flag CI failure, like the Travis config above does.

Thanks.

@madhurig any news?

[cclauss]

I would not call this Python Latest but would instead call it Python Nightly.

Is this a duplicate of #20?

It has a workaround to use deadsnakes: #20 (comment).

[asottile]

there's now a slightly better workaround using deadsnakes/action

This should really be offered "natively" by setup-python.

Agreed, having 3.12-alpha available would be a big win. Especially since xapian fails to build and a
number of other deprecated features like cgi are removed IIRC in 3.12 and they need testing.

3.12 has been released yesterday

@kelson42 This is only alpha 6, see https://peps.python.org/pep-0693/ for the full 3.12 release schedule.

@pquentin ooops. Thx
