如何从解析后的json中提取具有特定键的数据？

Question

我已经解析了json数据：

{
    "results": {
        "authors": [
            [
                {
                    "person": "Person1 Name",
                    "key": "director"
                }
            ],
            [
                {
                    "person": "Person2 Name",
                    "key": "author"
                },
                {
                    "person": "Person3 Name",
                    "key": "author"
                }               
            ]
        ]
    }
}

也就是说，可以有几位导演和几位作者。我应该把它做成细绳：

^{pr2}$

看起来我应该检查每个值并检查它的key。但是我怎么能用simplejson做到呢？在

以下代码适用于我：

authors = []
directors = []
for persons in movie_json.get('results').get('authors'):
    for person in person:
        if person.get('person'):
            if person.get('key')=='author':
                authors.append(person.get('person'))
            elif person.get('key')=='director':
                directors.append(person.get('person'))
authors = None if authors == [] else ', '.join(authors)
directors = None if directors == [] else ', '.join(directors)
