..............

Sometimes you want to loop through a dict,  doing something with
 each of the items.  For example you want to generate a report.
 

Suppose you have a dict where the keys are names and the values
 are grades. Perhaps you want to calculate the average grade.  You
 don't care about names,  so you loop through values.

Or you want to check how many names begin with J. Loop through the
 keys.
