[New-bugs-announce] [issue45671] str(CancelledError()) is empty

[lilydjwg]

New submission from lilydjwg <lilydjwg at gmail.com>:

When I try to print an asyncio.CancelledError object, I do not see it and I thought something went wrong.

CancelledError inherits from BaseException and all BaseException subclasses (e.g. SystemExit, KeyboardInterrupted) seem to return empty strings for str(e). While I never tried to print SystemExit or KeyboardInterrupted, I did try to print an CancelledError. It doesn't have a lot information but all other exceptions I tried to print return something so I expect CancelledError to be the same.

I know repr(e). I was just lazy and I expect Python to not be confusing even I'm lazy.
