Riccardo Coccioli added the comment: This can actually be reproduced with Python 2.7 too (thanks @thiell to let me know). At first I thought that it was not because it doesn't repro with the stock macOS-shipped Python 2.7.10 on macOS Sierra 10.12.6, where the select.poll() is not available at all, see below.
Updated list of version where I was able to reproduce the error: - macOS Sierra 10.12.6 with those Python versions: 2.7.10, 2.7.13, 3.3.6, 3.4.6, 3.5.3, 3.6.2, 3.7.0a0 (heads/master:2ef37607b7) - FreeBSD 11.1 with those Python versions: 2.7.13, 3.7.0a0 (heads/master:2ef37607b7) For reference, the repro code executed with the stock macOS-shipped Python: #------ $ /usr/bin/python Python 2.7.10 (default, Feb 7 2017, 00:08:15) [GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.34)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import select >>> p = select.poll() Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'module' object has no attribute 'poll' #------ If the PR 3277 that I've sent against the master branch with the fix will be accepted, I'm ready to send additional PRs to backport the fix in all affected versions. ---------- versions: +Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue31334> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
