Zachary Ware added the comment: I suspect you may have a file shadowing the standard library's types.py; you can test with the following command:
python -c "import types;print(types.__file__)" If the output from that is not "C:\Python33\lib\types.py", then you have another file shadowing it, which would best be renamed. ---------- nosy: +zach.ware status: open -> pending _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19947> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
