+A new built-in function, \function{enumerate()}, will make

+\var{thing} is either an iterator or a sequence, returns a iterator

+\var{thing[1]})}, \code{(2, \var{thing[2]})}, and so forth. Fairly
+often you'll see code to change every element of a list that looks
+like this:

+\begin{verbatim}
+for i in range(len(L)):

+ # ... compute some result based on item ...
