python - 构建 JSON 格式时出现问题。在字典和集合之间选择？

Question

我正在构建 json 格式，预期如下:

{   
 accounts:[   {
      "acctnum": "acct1",
      "key2":"value2"
      "key3": []
      "summary" : {
          //nested dict
      }
    }

   ]  //if we have 1 account for given customer     
}

如果我们为客户拥有多个帐户:

{   
 accounts:[   {
      "acctnum": "acct1",   // for acct1
      "key2":"value2"
      "key3": []
      "summary" : {
          //nested dict
      }
    },
    {
        "acctnum": "acct2",   //for acct2
        "key2":"value3"
        "key3": []
        "summary" : {
            //nested dict
        }
      }  
    ]       
}

在使用acct1所需的属性构建字典后，我的代码接近尾声(并且有疑问我是否应该使用集合模块):

acctlist = []
acctlist = results  //results is dict for acct1 (with nested dict)
print(acctlist)
accounts  = {}
accounts["accounts"] = acctlist
j = json.dumps(accounts, indent=4)
print(j)

但实际的 json 格式如下:

{   
 accounts: {
      "acctnum": "acct1",
      "key2":"value2"
      "key3": []
      "summary1" : {
          //nested dict
      }
    }   
}

您的打印声明可能回答了您的问题。这是一个列表吗？

acctlist = []
acctlist = results  //results is dict for acct1 (with nested dict)
print(acctlist)

我怀疑你的意思是acctlist.append(results)
