我正在尝试将从网站抓取的 JSON 文件读取到 Python 中,最终目标是将其转换为 csv 文件以供以后进行统计分析。
我要读取的文件示例是:

我当前的代码如下所示(之前的复制和粘贴作业莫名其妙地错误):
import json
from pprint import pprint
json_data = open('/home/readejj/Documents/data/1-1-jFEwehyT-1-2-yjaf9.dat').read()
json_stuff = json_data[json_data.find('{'):json_data.rfind('}')+1]
json_stuff = json_stuff.replace("\"","'")
print "json_stuff",type(json_stuff), len(json_stuff), json_stuff[1:2000]
d = json.loads(json_stuff)
pprint(d)
这是采用自:Reading JSON from a file?
我收到的错误是:
Traceback (most recent call last):

如果有人可以提供帮助,我们将不胜感激 - 如果这是一个非常基本的错误,我很抱歉,我不是一个经验丰富的程序员。
更新:有人指出我的替换行不好 - 如果删除,我会收到不同的错误:
Traceback (most recent call last):

最佳答案
这一行:
json_stuff = json_stuff.replace("\"","'")
很糟糕。删除它。
JSON 规范要求字符串用双引号 ("
) 分隔,而不是单引号。
