I've decided to take an easy path: https://github.com/python/cpython/pull/28310 ``` PyErr_Format(PyExc_ValueError, "Invalid format specifier: '%s' for object of type '%s'", PyUnicode_AsUTF8AndSize(format_spec, NULL), Py_TYPE(obj)->tp_name); ``` This worked for me as the starting point. It covered: int, float, complex, and str types. > Note that in your original example, you want the error to contain > "{length:%HH:%MM}". By the time the error is detected, the only thing the > code knows is the format specifier "%HH:%MM". It doesn't know the "length" > part. I guess it has changed since the 2014. I would love to hear any feedback on my proposal and improve it to the level when it can be merged :) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue20524> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
