New submission from Vincent Lefoulon <vincent.lefou...@free.fr>:
When we call `json.dumps` on a non JSON serializable object, we obtain an error: ``` TypeError: 4 is not JSON serializable ``` Here, 4 was actually a `numpy.int64` object and not a native int. But it is not explicit in the error message. We should mention the type of the object as well: ``` TypeError: 4 of type numpy.int64 is not JSON serializable ``` ---------- messages: 320570 nosy: Vayel priority: normal severity: normal status: open title: Display type of not JSON serializable object type: enhancement versions: Python 3.5 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33979> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
