title: Python JSON to CSV not working
body: <p>I am having trouble to convert json to CSV. 
  I am kinda new to JSON parsing. All I want is to get from
  my JSON some "pretty" csv. So I can have data that I can read.</p>
  
  <p>I am trying </p>
  
  <pre><code>f = csv.writer(open('data.csv', 'w+', encoding='utf-8', newline=''))
  for item in json_head:
      f.writerow(item)
  </code></pre>
  
  <p>but all I get in <code>data.csv</code> is </p>
  
  <pre><code>d,a,t,a
  i,n,c,l,u,d,e,d
  l,i,n,k,s
  m,e,t,a
  </code></pre>
  
  <p>Json template that's in documentation looks like this</p>
  
  <pre><code>{
    "data": {
      "type": "string",
      "id": "string",
      "attributes": {
        "createdAt": "string",
        "duration": 0,
        "gameMode": "string",
        "patchVersion": "string",
        "shardId": "string",
        "stats": {},
        "tags": {},
        "titleId": "string"
      },
      "relationships": {
        "assets": {
          "data": [
            {
              "type": "string",
              "id": "string"
            }
          ]
        },
        "rosters": {
          "data": [
            {
              "type": "string",
              "id": "string"
            }
          ]
        },
        "rounds": {},
        "spectators": {}
      },
      "links": {
        "schema": "string",
        "self": "string"
      }
    },
    "included": [
      null
    ],
    "links": {
      "first": "string",
      "previous": "string",
      "self": "string",
      "next": "string"
    },
    "meta": {}
  }

  <p>And part of real JSON I received via API looks like this</p>
  
  <pre><code>{"data":

  </code></pre>
  
  <p>For beginning it's enough if there is a way to get data from specific elements, for me those are these elements <code>"type":"participant"</code>
  And I would expect tabular data like this </p>
  
  <pre><code>ID                                    |DBNOs | assists | boosts | othercolumns from "stats"
  f0d889c7-49e7-4c83-ac0b-d7f23d13e09f  | 3    |   0     |   2    |
  5c26da97-6733-49d4-8a56-5dc7513e3c77  | 0    |   0     |   0    |
  </code></pre>
  
  <p>I know I could hardcode some code to parse it, I am just looking for every possibility. </p>
  
  <p>Thanks</p>
