Python Counter Comparison as Bag-type

by

On Python 2, the comparison falls back to the default sort order for dictionaries (Counter is a subclass of dict).

Mappings (dictionaries) compare equal if and only if their sorted
(key, value) lists compare equal. [5] Outcomes other than equality are
resolved consistently, but are not otherwise defined. [6]

On Python 3, the comparison raises a TypeError:

Mappings (dictionaries) compare equal if and only if they have the
same (key, value) pairs. Order comparisons (‘<‘, ‘<=’, ‘>=’, ‘>’)
raise TypeError.
