Re: Sad news: Fredrik Lundh ("Effbot") has passed away
Like many others, I'm saddened to hear of Fredrik Lundh's passing. I vaguely recall meeting him just once, probably at a Python workshop, before they grew big enough to be called conferences. Effbot.org was my Tkinter, ElemenTree, and PIL reference and cheat sheet. My attention to Python development has waxed and waned over the years. Most of the time, the trip through the Python folder in my mail program was generally pretty quick, hitting the 'd' key far more often than I'd stop to read a message. There are only a few people whose messages I'd always read. Effbot was one. In my opinion, Fredrik ranks up there with Guido, Tim Peters and Barry Warsaw. I went to effbot.org and saw the "on hiatus" message. Searching through The Wayback Machine, it seems it went on hiatus in late November, 2020. The 11 November 2020 snapshot appears to be the last usable version: https://web.archive.org/web/2020145627/http://effbot.org/ Probably worth a bookmark in your browser. Rest easy /F ...

Re: Isn't TypeError built in?
Yes, TypeError is built in. The only thing I can think of is that something has deleted `TypeError` from `__builtins__`? It would be interesting to see what's in `__builtins__` when `__del__` is called.

During interpreter shutdown, all kinds of things can go weird. The order that things get destroyed isn't always clearly defined. Is it possible to do the cleanup work before interpreter shutdown? Alternatively: maybe take a local reference to the exception types you need to refer to (just "AttributeError = AttributeError" at top level should do it), which should keep them alive longer (I think). Worst case, capture *all* exceptions, then look at e.__class__.__name__ and match on that. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
