Iterator Example From Dive Into Python 3

I'm learning Python as my 1st language from http://www.diveintopython3.net/. On Chp 7, http://www.diveintopython3.net/iterators.html, there is an example of how to use an iterator.

Solution 1:

The return statement ends the function at that point, returning a value to the caller. This can be relied upon in almost any situation (if you have a try..except..else..finally structure, even a return statement won't prevent the finally block from being executed).
