I disagree, but does not insists if other core developers have other opinion. This is a special case which breaks the rules. The Python language specification does not support non-string keywords. You cannot implement this "feature" in Python. And it is not compatible with other implementations (PyPy): >>>> ''.format(**{1:2}) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: format() keywords must be strings, not 'int' It would be understandable to not enforce this limitation if it has significant costs. But in this case it costs almost nothing. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39694> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
