OP should have had offers pouring in: "using and teaching Python for over 20 years, and designed its built-in set module, but nobody would hire me as a Python programmer when I was laid off by RStudio in February."
If OP can't get an offer(for Python!) then something is really wrong. Where? Possibly they could not get past some silly HR filter.
If you were a Python shop wouldn't you want to have an interview with OP would you?
There is an advice floating around HN that one should contribute meaningfully to some popular open source project and/or write a book about something -> leading to better career prospects.
The above might be helpful but clearly not sufficient. (I've seen good book authors still looking for job prospects)
