Martin Panter added the comment: The Python documentation refers to RFC 3986, which allows an empty port string introduced by a colon, although it recommends against it: <https://tools.ietf.org/html/rfc3986#section-3.2.3>
The “port” subcomponent of “authority” is designated by an optional port number in decimal following the host and delimited from it by a single colon. . . . URI producers and normalizers should omit the port component and its “:” delimiter if “port” is empty . . . What problem are you trying to solve by raising an error? See also Issue 20059, where accessing the “port” field now raises ValueError for out-of-range values, and Issue 20271, discussing invalid URL handling more generally. ---------- nosy: +martin.panter _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28841> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
