python - JSON解码错误: Extra data: line 1 column 228 (char 227)

Question

我正在使用 Ipython 进行一些数据分析，我无法加载 JSON 文件。请帮我在 IPython 中加载这个 JSON 文件。 我还想跳过第一行中的相同单词以使其成为干净的格式，我希望每条记录如下所示:

{"station_id":"72","num_bikes_available":18,"num_bikes_disabled":0,"num_docks_available":20,"num_docks_disabled":1,"is_installed":1,"is_renting":1,"is_returning":1,"last_reported":"1467164372","eightd_has_available_keys":false},

这是我的代码:

In [9]: path = 'stationstatus.json'

In [10]: records = [json.loads(line) for line in open(path)]

这是错误:

JSONDecodeError                           Traceback (most recent call last)
<ipython-input-10-b1e0b494454a> in <module>()
----> 1 records = [json.loads(line) for line in open(path)]  
<ipython-input-10-b1e0b494454a> in <listcomp>(.0)
----> 1 records = [json.loads(line) for line in open(path)]
//anaconda/lib/python3.5/json/__init__.py in loads(s, encoding, cls, object_hook, parse_float, parse_int, parse_constant, object_pairs_hook, **kw)
317             parse_int is None and parse_float is None and
318             parse_constant is None and object_pairs_hook is None and not kw):
--> 319         return _default_decoder.decode(s)
320     if cls is None:
321         cls = JSONDecoder
//anaconda/lib/python3.5/json/decoder.py in decode(self, s, _w)
340         end = _w(s, end).end()
341         if end != len(s):
--> 342             raise JSONDecodeError("Extra data", s, end)
343         return obj
344 

这是我的 JSON 文件的一部分**:

以下是加载文件的建议:

with open('Path/to/file', 'r') as content_file:
    content = content_file.read()
records = json.loads(content)

json 中的根对象将位于您的 records 变量中
