New submission from Irit Katriel <[email protected]>:
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.__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).
