Lib/logging/config.py has this, which looks like it's partly remnants of old exception handling APIs: except ImportError: e, tb = sys.exc_info()[1:] v = ValueError('Cannot resolve %r: %s' % (s, e)) v.__cause__, v.__traceback__ = e, tb raise v It is clearer if written as: except ImportError as e: v = ValueError('Cannot resolve %r: %s' % (s, e)) raise v from e (note that this doesn't copy the traceback from e to v, but this is redundant information anyway because e is chained to v as the cause). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46332> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
