Python-使用for循环通过json对象打印

所以我一直在做一种显示器-什么显示器是每当一个新的项目,对象,数字是新的,然后打印出来基本上没有什么伤害。

"threads": {
    "1": {
        "name": "Hello",
        "id": "4174"
    },
    "2": {
        "name": "World",
        "id": "6231"
    },
    "3": {
        "name": "Overflow",
        "id": "7231"
    }
}

def get_feed():

    url = 'https://www.helloworld.com/loadfilter'
    resp = s.get(url, timeout=6)
    resp.raise_for_status()

    return resp.json()['threads']

old_list = []

for index, thread in get_feed().items():
    old_list.append(thread['id'])

while True:
    try:

        new_list = []
        for index, thread in get_feed().items():
            new_list.append(thread['id'])

        for index, item in enumerate(new_list):
            if item in old_list:
                print(item['name'] # ERROR - string indices must be integers

        else:
            print('Sleeping 2 sec')
            time.sleep(2)


    except Exception as e:
        print(e)


sys.exit()

所以基本上如果我在 for index, thread in get_feed().items(): 印刷品 thread['name'] 这不是问题,它会打印出来。

if item in old_list:

意思是:每当我在 if item old list 等等,['name']它应该给出名字吗?
