There seems to have been increased interest in good error recovery over
the last years. I thought I had bookmarked a bunch of projects, but the
only one I can find right now is Lezer
(https://marijnhaverbeke.nl/blog/lezer.html) which is part of the
CodeMirror (https://codemirror.net/) editor. Python is listed as a
currently supported language, so you might want to check that out.

Disclaimer: I haven't used CodeMirror, so I can't say anything about
its quality. The blog entry about Lezer was interesting, though.
