I am calling an API and I am getting a JSON response like the one above:

```
{
  "data": {
    "styles": [
      {
        "groups": [
          {
            "product": [
              {
                "code": "0000001",
                "date": null
              }
            ]
          },
          {
            "product": [
              {
                "code": "0000002",
                "date": "2020-05-02T00:00:00.000Z"
              }
            ]
          },
          {
            "product": [
              {
                "code": "0000003",
                "date": "2020-04-22T00:00:00.000Z"
              }
            ]
          }
        ]
      },
      {
        "groups": [
          {
            "product": [
              {
                "code": "0000011",
                "date": "2020-05-12T00:00:00.000Z"
              }
            ]
          },
          {
            "product": [
              {
                "code": "0000012",
                "date": "2020-05-12T00:00:00.000Z"
              }
            ]
          }
        ]
      }
    ]
  }
}

```

I am not familiar with handling JSON and this one is super nested. All I want to do is to create a tuple (or a dict) which would look like:

```
(0000001, null)
(0000002, 2020-05-02T00:00:00.000Z)
(0000003, 2020-04-22T00:00:00.000Z)
(0000011, 2020-05-12T00:00:00.000Z)
(0000012, 2020-05-12T00:00:00.000Z)

```

Could you please advice me one how to do that?
