>>> email.utils.parsedate_to_datetime(None) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/serhiy/py/cpython/Lib/email/utils.py", line 200, in parsedate_to_datetime raise ValueError('Invalid date value or format "%s"' % str(data)) ValueError: Invalid date value or format "None" First, the date value is None, not "None". Second, why not just return None? parsedate() can be used in code like: parsedata(headers.get('Date')) None is an expected argument if the header "Date" is absent. parsedate_to_datetime() is not compatible with parsedata() in this case. It was a regression introduced in issue16714. Before that parsedate_to_datetime(None) returned None. ---------- nosy: +serhiy.storchaka status: closed -> open _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue30681> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
