json文件内容如下:

{"votes": {"funny": 0, "useful": 5, "cool": 2}, "user_id": "rLtl8ZkDX5vH5nAx9C3q5Q", "review_id": "fWKvX83p0-ka4JS3dc6E5A", "stars": 5, "date": "2011-01-26", "text": "My wife took me here on my birthday for breakfast and it was excellent.  It looked like the place fills up pretty quickly so the earlier you get here the better.\n\nDo yourself a favor and get their Bloody Mary. It came with 2 pieces of their griddled bread with was amazing and it absolutely made the meal complete.  It was the best \"toast\" I've ever had.\n\nAnyway, I can't wait to go back!", "type": "review", "business_id": "9yKzy9PApeiPPOUJEtnvkg"}
{"votes": {"funny": 0, "useful": 0, "cool": 0}, "user_id": "0a2KyEL0d3Yb1V6aivbIuQ", "review_id": "IjZ33sJrzXqU-0X6U8NwyA", "stars": 5, "date": "2011-07-27", "text": "I have no idea why some people give bad reviews about this place. It goes to show you, you can please everyone. They are probably griping about something that their own fault... but they said we'll be seated when the girl comes back from seating someone else. So, everything was great and not like these bad reviewers. That goes to show you that  you have to try these things yourself because all these bad reviewers have some serious issues.", "type": "review", "business_id": "ZRJwVLyzEJq1VAihDhYiow"}

我的代码是:

^{pr2}$

错误是:

Traceback (most recent call last):
  File "/Users/hadoop/Documents/workspace/dataming-course/src/Yelp/main.py", line 8, in <module>
    data = json.load(review)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/__init__.py", line 278, in load
    **kw)

不管怎样,您可以尝试将JSON放入数组中,如下所示:

[ { "business_id" : "9yKzy9PApeiPPOUJEtnvkg",
    "date" : "2011-01-26",
    "review_id" : "fWKvX83p0-ka4JS3dc6E5A",
    "stars" : "5",
    "text" : "My wife took me here on my birthday for breakfast and it was excellent.  It looked like the place fills up pretty quickly so the earlier you get here the better.\n\nDo yourself a favor and get their Bloody Mary. It came with 2 pieces of their griddled bread with was amazing and it absolutely made the meal complete.  It was the best \"toast\" I've ever had.\n\nAnyway, I can't wait to go back!",
    "type" : "review",
    "user_id" : "rLtl8ZkDX5vH5nAx9C3q5Q",
    "votes" : { "cool" : "2",
        "funny" : "0",
        "useful" : "5"
      }
  },
  { "business_id" : "ZRJwVLyzEJq1VAihDhYiow",
    "date" : "2011-07-27",
    "review_id" : "IjZ33sJrzXqU-0X6U8NwyA",
    "stars" : "5",
    "text" : "I have no idea why some people give bad reviews about this place. It goes to show you, you can please everyone. They are probably griping about something that their own fault... but they said we'll be seated when the girl comes back from seating someone else. So, everything was great and not like these bad reviewers. That goes to show you that  you have to try these things yourself because all these bad reviewers have some serious issues.",
    "type" : "review",
    "user_id" : "0a2KyEL0d3Yb1V6aivbIuQ",
    "votes" : { "cool" : "0",
        "funny" : "0",
        "useful" : "0"
      }
  }
]

(注意分隔JSON数组的两个“main”部分的,

在一个文件中有两个JSON文档。考虑将它们放入数组或其他东西中。文件的顶层应该只包含一个元素。在

{t}你可以在文件中使用{cd1}更改它。在

>>> dec = json.JSONDecoder()
>>> dec.raw_decode('["a",1]{"foo": 2}')
(['a', 1], 7)
>>> dec.raw_decode('["a",1]{"foo": 2}', 7)
({'foo': 2}, 17)

您需要先将文件读入字符串。在
