How to generate specific JSON from python dict?

Question

I want to create json data which exactly looks like this:

[
      {
        "mainDetail": {
            "number": "12345",    
            "inStock": 111
        }
      },
      {
        "mainDetail": {
            "number": "54321",
            "inStock": 222
        }
      }
]

The data "number" and "instock" are read from python dict:

articleDict = {}
d=[{'number': x, 'inStock': y} for x,y in articleDict.items()]
print json.dumps(d, indent=4)

This is what i get so far:

[
    {
        "number": "12345",
        "inStock": 111
    },
    {
        "number": "54321",
        "inStock": 222
    }
]

I am just missing the "mainDetail" , I'm at an impasse with my ideas. What can I do to make it work?

Answer 1

d=[{"mainDetail" : {'number': x, 'inStock': y}} for x,y in articleDict.items()]

创建列表时，您需要添加此“mainDetail”。
