python - 如何解析python中某个部分内包含列表的json文件？

Question

我有一个 smaple.json 如下:

{"Detail":[
    {
    "DocType":"txt",
    "Name":"hello.txt",
    }
    ]}

我需要“名称”字段的值。我在我的脚本中尝试如下:

file="c:/sample.json"
for list in file:
    if (str(list['Detail'])=='None'):
         print("Do nothing")
     else:
         ana = list['Detail']
         val =  (str(ana)[1:-1])
         print val
         print val['Name']

我得到的输出为:

  {"DocType":"txt","Name":"hello.txt"} 
  error:print (ana['Name'])
  TypeError: string indices must be integers

那么我做错了什么，我该如何获取“名称”字段详细信息。

您可以使用json库:

import json

json_path = "c:\\sample.json"
with open(json_path) as json_file:
    json_dict = json.load(json_file)

name = json_dict['Detail'][0]['Name']
