如何从movie.get（'casts'）函数中获取名称

Question

嗨，我正在尝试使用IMDbPY库创建一个数据库。但当我试图用get（'cast'）获取name时。 我怎样才能修好它？代码如下：

from imdb import IMDb
ia = IMDb()
def getmovieID( movie_name ):
    movie = ia.search_movie(movie_name)[0] # a Movie instance.
    get_movie = ia.get_movie(movie.movieID)
    return get_movie

def getcast(movie_name):
    movie = getmovieID(movie_name)
    casts = []
    cast = movie.get('casts')
    for a in cast['name']:
        casts.append(a)
    return casts

print(getcast('The Dark Knight'))

它说： getcast中第17行的文件“C:…/Python/imdbtest.py” 对于内播['name']：

TypeError:字符串索引必须是整数

重构代码

from imdb import IMDb
ia = IMDb()


def getmovieID(movie_name):
    movie = ia.search_movie(movie_name)[0]
    get_movie = ia.get_movie(movie.movieID)
    return get_movie


def getcast(movie_name):
    movie = getmovieID(movie_name)
    casts_objects = movie.get('cast')
    casts = []
    for person in casts_objects:
        casts.append(person.get('name'))
    return casts

print(getcast('The Dark Knight'))
