[issue43146] 3.10a5 regression: AttributeError: 'NoneType' object has no attribute '__suppress_context__' in traceback.py

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

It seems to me that print_exception(None), etc, *should* raise something.  Printing "NoneType: None\n" makes no sense to me since NoneType is not an exception.  In 3.9, it raised TypeError for # of arguments.

I do note that in 3.9
>>> traceback.print_exception(None, None, None)
NoneType: None

I wonder what the rationale was.  It isn't because these functions never raise.
