Pythonのデータ分析のためのエラー：期待値：行1列1（CHAR 0）

Question

Iはデータ解析と第一実施例のためのPythonの例に沿って以下AMは示しています

In [15]: path = 'ch02/usagov_bitly_data2012-03-16-1331923249.txt' 
In [16]: open(path).readline() 
Out[16]: '{ "a": "Mozilla\\/5.0 (Windows NT 6.1; WOW64) AppleWebKit\\/535.11 
(KHTML, like Gecko) Chrome\\/17.0.963.78 Safari\\/535.11", "c": "US", "nk": 1, 
"tz": "America\\/New_York", "gr": "MA", "g": "A6qOVH", "h": "wfLQtf", "l": 
"orofrog", "al": "en-US,en;q=0.8", "hh": "1.usa.gov", "r":

1331822918, "cy": "Danvers", "ll": [ 42.576698, -70.954903 ] }\n' 

Iを得る手順に従った後：

In [21]: open(path).readline() 
Out[21]: '{ "a": "Mozilla\\/5.0 (Windows NT 6.1; WOW64) AppleWebKit\\/535.11 
(KHTML, like Gecko) Chrome\\/17.0.963.78 Safari\\/535.11", "c": "US", "nk": 1, "

42.576698, -70.954903 ] }\n' 

唯一の違いは、「」部分です。

その後、私がしようとすると：

は

import json 
path = 'ch02/usagov_bitly_data2012-03-16-1331923249.txt' 
records = [json.loads(line) for line in open(path)] 

...私が得るものです：私はこのJSONDecodeErrorエラーを取得する理由

`In [22]: import json

JSONDecodeError: Expecting value: line 1 column 1 (char 0)` 

いずれかを知っていますか？

Answer 1

JSON形式ではありませんが、あなたは異常なテキストを削除するか、オンライン形式のJSONをより明確にする必要があります。
