Yes, that's what I just said. "Z" is just (an approximation of!) a symbol that means "the set of integers". > (as is float, technically, though that particular subset has no nice > name like Z and Q) The operators that apply to it are the operations > on R, even operations under which Z (or even R) is not closed. No, in Python integers are closed under the standard arithmetic operators (+ - * / % **) - except, since Python 3, for "/", which is now a special case. -- https://mail.python.org/mailman/listinfo/python-list
