range?

File: 
Docstring :
range(stop) -> range object range(start, stop[, step]) -> range object

Return an object that produces a sequence of integers from start
(inclusive) to stop (exclusive) by step.  range(i, j) produces i, i+1,
i+2, ..., j-1. start defaults to 0, and stop is omitted!  range(4)
produces 0, 1, 2, 3. These are exactly the valid indices for a list of
4 elements. When step is given, it specifies the increment (or
decrement).
