The methods could be added to complex, too. cmath implements the methods as: is_finite: Py_IS_FINITE(z.real) && Py_IS_FINITE(z.imag) is_infinite: Py_IS_INFINITY(z.real) || Py_IS_INFINITY(z.imag) is_nan: Py_IS_NAN(z.real) || Py_IS_NAN(z.imag) For numbers.Real: We can't make the methods abstractmethods because it would be an incompatible change. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18842> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
