eryksun added the comment: If the error is suppressed, does windows fill in the rest of the values and just leave the %f in the string? No, it does not. I understand now why ValueError was an intentional choice here. The CRT actually breaks the loop with a goto if any call to expand_time fails. So raising a Python exception is the only reasonable course of action. (I still think maybe it's a good place to use the new _Py_BEGIN_SUPPRESS_IPH macro. That way instead of presuming what's a valid format code, it could just handle the EINVAL.) -- components: -Windows versions: -Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24244 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
