[issue24797] email.header.decode_header return type is not consistent
R. David Murray added the comment: Right, it's provisional in 3.4. I'm working on the doc rewrite now (although I suppose there's a chance it won't get accepted for 3.5, I expect it to). Take a look at https://docs.python.org/3/library/email.policy.html. Basically, if you use EmailMessage instead of Message (and therefore policy.default instead of policy.compat32) header parsing and decoding is handled for you. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24797 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Sebastian Kreft added the comment: And what would the new API be? There is nothing pointing to it either in the documentation https://docs.python.org/3.4/library/email.header.html or source code. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24797 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue24797] email.header.decode_header return type is not consistent
New submission from Sebastian Kreft:
The return type of email.header.decode_header is not consistent. When there are
encoded parts the return type is a list of (bytes, charset or None) (Note that
the documentation says it is a list of (str, charset)). However, when there are
no encoded parts the return type is [(str, None)]. Note that, at the end of the
function, there is a routine that converts everything to bytes.
Compare:
In [01]: email.header.decode_header('=?UTF-8?Q?foo?=bar')
Out[01]: [(b'foo', 'utf-8'), (b'bar', None)]
In [02]: email.header.decode_header('foobar')
Out[02]: [('foobar', None)]
