[Python-Dev] The repr of a sentinel

Following a recent change, we now have in traceback.py: _sentinel = object() def print_exception(exc, /, value=_sentinel, tb=_sentinel, limit=None, file=None, chain=True): So now: >>> import traceback >>> help(traceback.print_exception) Help on function print_exception in module traceback: print_exception(exc, /, value=<object object at 0x000002825DF09650>, tb=<object object at 0x000002825DF09650>, limit=None, file=None, chain=True) Is there a convention on how such default sentinel values should appear in docs? https://bugs.python.org/issue43024
