Bill Bergmann added the comment: Thank you for your response. The program works as expected.
I removed PYTHONPATH settings for 3.4 and 2.7. I'm not sure how those settings were written. I suspect something related to virtualenv, and I will be watching to see if they are written again. When I removed those paths, an error message pointed me to a local version of concurrent.py from tornado that was shadowing the concurrent.py in the python3.4 site-packages. ---------- resolution: -> not a bug status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21378> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
