New submission from couplewavylines: In io.StringIO, the newline argument's default is currently documented as "newline=None" in the section header. However, it's described this way: "The default is to do no newline translation." The behavior of io.StringIO is consistent with this description (NO newline translation). The header should actually read "newline=''". "newline=None" would mean there IS newline translation by default, which is not the case. Code sample attached as no_translation.py. ---------- assignee: docs@python components: Documentation files: no_translation.py messages: 209577 nosy: couplewavylines, docs@python priority: normal severity: normal status: open title: io.StringIO newline param has wrong default type: behavior versions: Python 3.3, Python 3.4 Added file: http://bugs.python.org/file33779/no_translation.py _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue20423> _______________________________________
