我正在使用python 3，正在尝试从json查询中访问某些信息。目前，我可以通过循环访问付款中的数据。我尝试执行相同的操作来访问order_status，但这是行不通的。
Json：
___order details___

我有一个名为data的变量：data = json.loads（self.rfile.read（length）.decode（'utf-8'））
我还有另一个变量order_payments = data ['payments'] 我可以循环浏览并访问is_declined
我想要一个名为order_status = data ['order_status']的变量，然后循环访问该变量以访问名称。我在order_status = data ['order_status']上遇到关键错误，但我不知道为什么。
