 Ever since Python 1.4 the slice syntax has supported a third
-``stride'' argument, but the builtin sequence types have not supported
-this feature (it was initially included at the behest of the

-2.3.

+For example, to extract the elements of a list with even indexes:
+
+\begin{verbatim}
+>>> L = range(10)
+>>> L[::2]
+[0, 2, 4, 6, 8]
+\end{verbatim}

+To make a copy of the same list in reverse order:

+\begin{verbatim}
+>>> L[::-1]
+[9, 8, 7, 6, 5, 4, 3, 2, 1, 0]
