- 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

- *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*

- step`` greater than *stop*. *step* must not be zero (or else :exc:`ValueError`
