Anders Hovmöller <bo...@killingar.net> added the comment: For `foo(a, /, b)`, it could be:
"TypeError: foo() missing 1 required argument 'a', and one required positional argument 'b'. If we start on this road there are some more, like for `def foo(a, *, b)` you get the error "TypeError: foo() missing 1 required positional argument: 'a'" which leaves out that the keyword only argument is also required. Another solution would be something like: TypeError: foo() missing 3 required arguments: 'a' (positional only), 'b', 'c' (keyword only) This solution scales to the worst complex cases, and is a lot clearer imo. Could even be further improved with some nicer formatting: TypeError: foo() missing 3 required arguments: 'a' (positional only) 'b' 'c' (keyword only) But that might be a bit overkill :) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46637> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
