最终目标：我想从我从Slack提取的JSON字符串中获取'userid'，'username'和'email'。当我尝试将它转换为列表时，它只会给我前三个键，它不会拉取嵌套的数据。将JSON字符串转换为列表以便列举
这里是我的代码：
from slackclient._client import SlackClient
import json
def main():
token = "XXXXX"
sc = SlackClient(token)
users = get_users(sc)
print(users)
print(list(users))
def get_users(sc):
print("Get Users")
print(80 * "=")
#call the users.list api call and get list of users
users = (sc.api_call("users.list"))
users = json.dumps(users)
users = json.loads(str(users))
return users
main()
我的问题是“打印（用户）”打印我出一个完整的JSON字符串和“打印（列表（用户））”只打印第一非嵌套键。这是我的输出结果的一个例子。
“打印（列表（用户））”给我下面的：
['members', 'cache_ts', 'ok']
“打印（用户）”给我的下面，但我不能撤出它的具体的事情作为一个字符串。
