I have some JSON data like:

```
{
  "status": "200",
  "msg": "",
  "data": {
    "time": "1515580011",
    "video_info": [
      {
          "announcement": "{\"announcement_id\":\"6\",\"name\":\"INS\\u8d26\\u53f7\",\"icon\":\"http:\\\/\\\/liveme.cms.ksmobile.net\\\/live\\\/announcement\\\/2017-08-18_19:44:54\\\/ins.png\",\"icon_new\":\"http:\\\/\\\/liveme.cms.ksmobile.net\\\/live\\\/announcement\\\/2017-10-20_22:24:38\\\/4.png\",\"videoid\":\"15154610218328614178\",\"content\":\"FOLLOW ME PLEASE\",\"x_coordinate\":\"0.22\",\"y_coordinate\":\"0.23\"}",
          "announcement_shop": "",

```

etc.

How do I grab the content `"FOLLOW ME PLEASE"`? I tried using

```
replay_data = raw_replay_data['data']['video_info'][0]
announcement = replay_data['announcement']

```

But now `announcement` is a string representing more JSON data. I can't continue indexing `announcement['content']` results in `TypeError: string indices must be integers`.

How can I get the desired string in the "right" way, i.e. respecting the actual structure of the data?
