New submission from Jonathan : https://docs.python.org/2/library/logging.handlers.html https://docs.python.org/3/library/logging.handlers.html Both say: """class logging.StreamHandler(stream=None) Returns a new instance of the StreamHandler class. If stream is specified, the instance will use it for logging output; otherwise, sys.stderr will be used.""" Surely that means from an user perspective that the default is actually `sys.stderr`, not `None`? ---------- assignee: docs@python components: Documentation messages: 347677 nosy: docs@python, jonathan-lp priority: normal severity: normal status: open title: Documentation - default for StreamHandler versions: Python 3.9 _______________________________________ Python tracker https://bugs.python.org/issue37563 _______________________________________
