   let's reserve a little time to discuss the in 
keyword (not an operator, as the text says, but 
that's not important): 
   the in keyword uses some feature of dictionaries 
to return values quickly; i'm guessing the feature 
is that of a hash table. recall our discussion last 
time was that the in keyword also uses features of 
lists and strings (sequences) and for all i recall 
(nothing further), the in keyword uses other 
features in other contexts. all in all seems helpful 
to review.
