New submission from Antony Lee: I noticed that while lzma and bz2 already support the "x" (create a new file, raise if it already exists) flag, zipfile and tarfile don't know about it yet. It would be an useful addition, just as it is useful for regular open.
A quick look at both modules show that this likely only requires a little bit more than updating the checks in the corresponding constructors to allow "x" mode, as the modes are passed (nearly) transparently to the open() builtin. ---------- components: Library (Lib) messages: 220249 nosy: Antony.Lee priority: normal severity: normal status: open title: Exclusive mode for ZipFile and TarFile versions: Python 3.4, Python 3.5 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21717> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
