I'm with you there--the use of "else" here has seemed a bit confusing to me.
The use case that Alex just posted gave me another way to think about it:
for item in allitems:
print "first fraboozable item is", item
print "Sorry, no item is fraboozable"
If I think of the else statement as being related to the if statement inside
the loop, then it makes some sense--the else statement is executed when the
if statement never comes up true. (It's twisted logic, I know, but at least
it helps me keep track of what "else" does here.)
