So I came across this today.. >>> class Number(object): ... def __init__(self, n): ... self.n = n ... >>> m = Number(10) >>> n = Number(5) >>> >>> m < n True
This is documented like so > If no __cmp__(), __eq__() or __ne__() operation is defined, class > instances are compared by object identity (“address”). over here https://docs.python.org/2/reference/datamodel.html#object.__cmp__ It seems a rather arbitrary thing to do. Why is it implemented at all? I'd expect it to just break with a TypeError similar to what would happen if I do >>> m + n Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: unsupported operand type(s) for +: 'Number' and 'Number' >>> -- Cordially, Noufal http://nibrahim.net.in _______________________________________________ BangPypers mailing list BangPypers@python.org https://mail.python.org/mailman/listinfo/bangpypers
