2.1.5.3 XRange Type

The xrange type is an immutable sequence which is commonly used for looping. The advantage of the xrange type is that an xrange object will always take the same amount of memory, no matter the size of the range it represents. There are no consistent performance advantages.

XRange objects behave like tuples, and offer a single method:

`tolist` ()
  Return a list object which represents the same values as the xrange object.
