[Tutor] I am terribly confused about "generators" and "iterators".. Help me

[Jonathon Sisson]

My understanding is that an iterator is basically a facade` pattern.  If 
you aren't familiar with patterns, a facade` pattern basically makes 
something really easy to use or convenient.  Yes, you can "do it by 
hand", and many times that is indeed the preferred method, but sometimes 
it's easier to use an iterator...particularly if it isn't a special 
case.  Nothing in the manual says you HAVE to use iterators, but they 
*can* make life easier.
