New submission from Seth Sims <seth.s...@gmail.com>:
_TemporaryFileWrapper does not proxy __next__ to the underlying file object. There was a discussion on the mailing list in 2016 mentioning this, however it seems it was dropped without a consensus. Biopython encountered this issue (referenced below) and we agree it violates our assumptions about how the NamedTemporaryFile should work. I think it would be fairly trivial to fix by just returning `self.file.readline()` mailing list thread: https://mail.python.org/pipermail/python-list/2016-July/862590.html biopython discussion: https://github.com/biopython/biopython/pull/3031 ---------- components: Library (Lib) messages: 373467 nosy: Seth Sims priority: normal severity: normal status: open title: NamedTemporaryFile is not its own iterator. type: behavior versions: Python 3.10, Python 3.5, Python 3.6, Python 3.7, Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41270> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
