-   This is a versatile function to create lists containing arithmetic progressions.
-   It is most often used in :keyword:`for` loops.  The arguments must be plain
-   integers.  If the *step* argument is omitted, it defaults to ``1``.  If the
-   *start* argument is omitted, it defaults to ``0``.  The full form returns a list
-   of plain integers ``[start, start + step, start + 2 * step, ...]``.  If *step*
-   is positive, the last element is the largest ``start + i * step`` less than
-   *stop*; if *step* is negative, the last element is the smallest ``start + i *
-   step`` greater than *stop*.  *step* must not be zero (or else :exc:`ValueError`
