Looking at the tempfile code more, I agree with Serhiy that changing it should be rejected. Python is a duck-typed language (essentially what Martin said). People should not be over-zealous in using instance checks. The doc specifically says that TemporaryFile returns a *file-like object* https://docs.python.org/3/glossary.html#term-file-like-object which only require implementing the interface. ---------- resolution: -> rejected stage: test needed -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33762> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
