Solve the following python programming problem given the following code:
def cache_region(region, * args) : 
    'Decorate a function such that its return result is cached,
    using a "region" to indicate the cache arguments.

    Example::

        from beaker.cache import cache_regions, cache_region

        # configure regions
        cache_regions.update({
            \'short_term\':{
                \'expire\':\'60\',
                \'type\':\'memory\'
            }
        })

        @cache_region(\'short_term\', \'load_things\')
        def load(search_term, limit, offset):
            \'\'\'Load from a database given a search term, limit, offset.\'\'\'
            return database.query(search_term)[offset:offset + limit]

    The decorator can also be used with object methods.  The ``self``
    argument is not part of the cache key.  This is based on the
    actual string name ``self`` being in the first argument
    position (new in 1.6)::

        class MyThing(object):
            @cache_region(\'short_term\', \'load_things\')
            def load(self, search_term, limit, offset):
                \'\'\'Load from a database given a search term, limit, offset.\'\'\'
                return database.query(search_term)[offset:offset + limit]

    Classmethods work as well - use ``cls`` as the name of the class argument,
    and place the decorator around the function underneath ``@classmethod``
    (new in 1.6)::

        class MyThing(object):
            @classmethod
            @cache_region(\'short_term\', \'load_things\')
            def load(cls, search_term, limit, offset):
                \'\'\'Load from a database given a search term, limit, offset.\'\'\'
                return database.query(search_term)[offset:offset + limit]

    :param region: String name of the region corresponding to the desired
      caching arguments, established in :attr:`.cache_regions`.

    :param \\*args: Optional ``str()``-compatible arguments which will uniquely
      identify the key used by this decorated function, in addition
      to the positional arguments passed to the...
