Martin Panter added the comment: You just need a messsage object with one or more header fields:
>>> msg = message_from_string("Name: value\r\n\r\n") >>> for m in msg: ... pass ... AttributeError: 'int' object has no attribute 'lower' Python 2 does not implement __iter__(), so it is the default sequence iteration protocol causing this behaviour. The documentation does not mention iteration either: <https://docs.python.org/2.7/library/email.message.html#email.message.Message.__len__>. It mentions a “mapping-like interface”, but since it explicitly lists __len__(), __contains__(), etc, and not __iter__(), I would say you should not assume iteration is supported. Python 3 does implement Message.__iter__(), but it does not seem to be documented. The method seems to be added as a side effect of Guido removing and restoring the email package: https://github.com/python/cpython/commit/1058618#diff-92a78c52ebc0a8908cbd06c8155f8bdb (removed without __iter__) https://hg.python.org/cpython/file/d5f3c2f416f2/Lib/email/message.py (added back including __iter__) ---------- nosy: +martin.panter title: int no attribute 'lower' -> int no attribute 'lower' iterating email.Messasge _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28881> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
