Pandas read_json()时报错ValueError: Trailing data

有一份json格式的文件，如下：

{
  "cover": "http://p2.music.126.net/wsPS7l8JZ3EAOvlaJPWW-w==/109951163393967421.jpg?param=140y140",
  "title": "2018上半年最热新歌TOP50",
  "author": "网易云音乐",
  "times": "1264万",
  "url": "https://music.163.com/playlist?id=2303649893",
  "id": "2303649893"
}
{
  "cover": "http://p2.music.126.net/wpahk9cQCDtdzJPE52EzJQ==/109951163271025942.jpg?param=140y140",
  "title": "你的青春里有没有属于你的一首歌？",
  "author": "mayuko然",
  "times": "4576万",
  "url": "https://music.163.com/playlist?id=2201879658",
  "id": "2201879658"
}

当我尝试用pd.read_json('data.json') 读取文件时，给我报错了，报错部分情况如下：

File "D:\python\lib\site-packages\pandas\io\json\json.py", line 853, in _parse_no_numpy
    loads(json, precise_float=self.precise_float), dtype=None)
ValueError: Trailing data

一顿百度后发现原来是 json 格式错误问题，也是头一回知道有 jsonviewer 这种东西。需要将文件里面的字典作为元素保存在列表当中才行，修改后如下。

[{
  "cover": "http://p2.music.126.net/wsPS7l8JZ3EAOvlaJPWW-w==/109951163393967421.jpg?param=140y140",
  "title": "2018上半年最热新歌TOP50",
  "author": "网易云音乐",
  "times": "1264万",
  "url": "https://music.163.com/playlist?id=2303649893",
  "id": "2303649893"
},
{
  "cover": "http://p2.music.126.net/wpahk9cQCDtdzJPE52EzJQ==/109951163271025942.jpg?param=140y140",
  "title": "你的青春里有没有属于你的一首歌？",
  "author": "mayuko然",
  "times": "4576万",
  "url": "https://music.163.com/playlist?id=2201879658",
  "id": "2201879658"
}]

还有另外一种方法就是文件的每一行为一个完整的字典，然后在函数中修改参数pd.read_json('data.json',lines=True)。lines 默认为 False ，设为 True后可以按行读取 json 对象。 在 pandas.read_json 文档 中是这样说明的：

lines : boolean, default False. Read the file as a json object perline.New in version 0.19.0.

修改后的 json 文件如下：
