That would be a behaviour change for 2.7, and an undesirable one. `str` loses precision in Python 2, so e.g., `json.loads(json.dumps(pi)) == pi` would no longer be true. (Indeed, the json library was changed to use `repr` rather than `str` for floats at some point in the past, for exactly this reason.) I assume that dbus.Double is a subclass of float. Is that correct? If that's the case, I'm a bit confused: `float.__repr__` behaves identically to `float.__str__` in Python versions >= 3.2, so I don't see what your suggested change would achieve. >>> class MyFloat(float): ... def __repr__(self): return "MyFloat(something_or_other)" ... def __str__(self): return "1729.0" ... >>> x = MyFloat(2.3) >>> import json >>> json.dumps(x) '2.3' ---------- nosy: +mark.dickinson _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27934> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
