How do I list all notes with a code block in a particular language with Dataview

What I’m trying to do

I’d like to select all notes that have a block with a particular language (e.g. python or dataview for that matter). Is it possible?

Things I have tried

There is a thread from '21 that says it is not supported. Perhaps it is now?

It’s not readily available as far as I know, but you can possibly do a search using the query searches. If not you’ll need to traverse the content of all notes.

I would suggest, if you’re vault is not to extensive, is to mark all relevant notes using either tags or fields in the frontmatter to mark them for later use.
