Fix syntax highlighting in README

[nicoddemus]

For some reason GH does not recognize .. code-block: python3, but .. code-block: python works even for Python 3 syntax.

Ugh. You're not wrong, but I bet this will break syntax highlighting on pypi, because pygments definitely treats python and python3 differently. Probably we should at least file bugs on GitHub and pygments asking them to fix their things.

[njsmith]

I emailed support@github.com, and filed https://bitbucket.org/birkenfeld/pygments-main/issues/1415

I guess I'll give it a few days to see if either of them seems to be moving :-)

Thanks, sorry I forgot to get back at this myself. 👍

Github just added python3 as an alias for python in the library they use for syntax highlighting: https://github.com/github/linguist/pull/4026

I'm not sure how long this will take to flow from "committed to the open source library" to "deployed on the production site" – possibly a few weeks.

[njsmith]

But in any case I guess I'll close this, since the current solution works with pypi/sphinx and the github rendering will fix itself eventually, and in the mean time it's not too terrible. Thanks for bringing this up though :-)

[nicoddemus]

Sure thing, thanks for the update!
