python 初学 读取文件

python 2.7 环境，读取一个 json字符串的文件，并解析。

创建一个json 文件 test.txt

{
    "Id": "zh-cn",
    "Name": "中国",
    "Date": "2018-02-02 23:59:59",
    "ArrayList": [
        {
            "AId": "1",
            "AName": "/tmp/1广东.txt",
            "Size": 1024
        },
        {
            "AId": "2",
            "AName": "/tmp/2广西.txt",
            "Size": 2048
        }
  ]
}

创建一个python 文件 readlist.py

#!/usr/bin/python
# -*- coding: UTF-8 -*- 
import json

oaslistfile=open('E:\\test','r')
linelist=oaslistfile.readlines();
linestrjoin = ''.join(str(e) for e in linelist)
print linestrjoin

load_json=json.loads(linestrjoin)
print load_json

for i in load_json["ArrayList"]:
    print i["AId"],i["AName"],i["Size"]

输出如下

>python "e:\readlist.py"
{
    "Id": "zh-cn",
    "Name": "涓浗",
    "Date": "2018-02-02 23:59:59",
    "ArrayList": [
        {
            "AId": "1",
            "AName": "/tmp/1骞夸笢.txt",
            "Size": 1024
        },
        {
            "AId": "2",
            "AName": "/tmp/2骞胯タ.txt",
            "Size": 2048
        }
  ]
}

{u'Date': u'2018-02-02 23:59:59', u'ArrayList': [{u'AId': u'1', u'AName': u'/tmp/1\u5e7f\u4e1c.txt', u'Size': 1024}, {u'AId': u'2', u'AName': u'/tmp/2\u5e7f\u897f.txt', u'Size': 2048}], u'Id': u'zh-cn', u'Name': u'\u4e2d\u56fd'}
