Guido van Rossum93817821995-01-17 16:01:01 +000028A range object represents an integer range. This is an immutable object;
Guido van Rossum12d12c51993-10-26 17:58:25 +000029a range cannot change its value after creation.

31Range objects behave like the corresponding tuple objects except that
32they are represented by a start, stop, and step datamembers.
