Python简单读取json文件功能示例

本文实例讲述了Python简单读取json文件功能。分享给大家供大家参考，具体如下：

read_json.json:

{
  "rule":{
    "namespace":"strategy",
    "name":"test_exp_1496234234223400",
    "version":0,
    "last_modify_time":1434234236819000,
    "log_rate":1023300,
    "schema_version":"hello_world!"
  }
}

read_json.py:

# -*- coding:utf-8 -*-
import json
with open("read_json.json", 'r') as f:
  temp = json.loads(f.read())
  print(temp)
  print(temp['rule'])
  print(temp['rule']['namespace'])

运行结果：

{u'rule': {u'name': u'test_exp_1496234234223400', u'log_rate': 1023300, u'namespace': u'strategy', u'schema_version': u'hello_world!', u'last_modify_time': 1434234236819000L, u'version': 0}}
{u'name': u'test_exp_1496234234223400', u'log_rate': 1023300, u'namespace': u'strategy', u'schema_version': u'hello_world!', u'last_modify_time': 1434234236819000L, u'version': 0}
strategy
