The keys to a dictionary may be any immutable type.  That includes str, 
int, and tuple, but it also can include any other class that meets a 
couple of simple criteria.  In simplified language, the only requirement 
is that the key object cannot change its value or hash, so that if two 
key objects are equal, they stay equal, and if they differ, they stay 
different.
