The counter is a subclass of the dict From collections library.

Counts are allowed to be any integer value including zero or negative counts. Even though it is fairly trivial to retrieve the least common elements in a Counter by doing Countermost_commonn-n-1 I believe that for the sake of consistency the least_common method should also be available.
