Mailman 3 The repr of a sentinel - Python-Dev

May 13, 2021

      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?
