Python将字典视为字符串

我正在做一个项目，在这个项目中，我需要从字典中的特定键获取值。但是，当我尝试访问该密钥时，会出现以下错误：

TypeError: string indices must be integers

我打开的词典在运行时如下所示：print（twit）：

有人能给我解释一下为什么Python将字典视为字符串吗

按要求打印结果（类型（twit）、报告（twit））：

您似乎拥有一个字符串而不是一个字典，而且它看起来像是有效的json，您可以使用模块将字符串加载到字典中，然后从中获取

id

。示例-

import json
twitdict = json.loads(twit)
print(twitdict['id'])

演示-
