POC for something we shouldn't do. is_anime could come from the API call, I think.

SeriesStatus.py

class _SeriesStatus:
    def __init__(self, is_anime):
        self.is_anime = is_anime

    def __repr__(self):
        return '{}(is_anime={})'.format(self.__class__.__name__, self.is_anime)
    
    def __str__(self):
        if self.is_anime:
            return self.anime_string
        else:
            return self.manga_string
            

class Started(_SeriesStatus):
    def __init__(self, is_anime):
        self.is_anime = is_anime
        self.status_code = 1
        self.manga_string = 'Publishing'
        self.anime_string = 'Currently Airing'

class Finished(_SeriesStatus):
    def __init__(self, is_anime):
        self.is_anime = is_anime
        self.status_code = 2
        self.manga_string = 'Finished'
        self.anime_string = 'Finished Airing'

class Planned(_SeriesStatus):
    def __init__(self, is_anime):
        self.is_anime = is_anime
        self.status_code = 3
        self.manga_string = 'Not Yet Published'
        self.anime_string = 'Not Yet Aired'

def Series(num, is_anime):
    if num == 1:
        return Started(is_anime)
    if num == 2:
        return Finished(is_anime)
    if num == 3:
        return Planned(is_anime)
    else:
        raise NameError


started_anime = Series(1, True)
finished_anime = Series(2, True)
planned_anime = Series(3, True)
started_manga = Series(1, False)
finished_manga = Series(2, False)
planned_manga = Series(3, False)

print(started_anime.status_code, str(started_anime), repr(started_anime))
print(finished_anime.status_code, str(finished_anime), repr(finished_anime))

print(finished_manga.status_code, str(finished_manga), repr(finished_manga))
print(planned_manga.status_code, str(planned_manga), repr(planned_manga))

'''
(1, 'Currently Airing', 'Started(is_anime=True)')
(2, 'Finished Airing', 'Finished(is_anime=True)')
(3, 'Not Yet Aired', 'Planned(is_anime=True)')
(1, 'Publishing', 'Started(is_anime=False)')
(2, 'Finished', 'Finished(is_anime=False)')
(3, 'Not Yet Published', 'Planned(is_anime=False)')
'''

__eq__ would also need to be overridden, I think.
