ConfigParser模块

对应配置文件：

[db]
db_host = 127.0.0.1
db_port = 3307
db_user = root
db_pass = password
db_none

[concurrent]
thread = 10
processor = 20

配置解析代码：

#!/usr/bin/env python2.7
#-*- coding:utf8 -*-

import ConfigParser
import string
import os
import sys

#支持没有空值
conf_par = ConfigParser.RawConfigParser(allow_no_value=True)
#conf_par = ConfigParser.ConfigParser()

conf_par.read("test.conf")

all_sections = conf_par.sections()
try:
        #所有模块
        print all_sections

        #获取所有options
        print conf_par.options("db")

        #获取对应的值 
        print conf_par.get("db","db_host")

        #获取int类型
        print conf_par.getint("db","db_port")
        print conf_par.get("db","db_none")

        #修改值
        conf_par.set("db","db_port","3307")
        conf_par.write(open("test.conf",'w'))
except ConfigParser.NoOptionError,e:
        print e

 结果输出：

['db', 'concurrent']
['db_host', 'db_port', 'db_user', 'db_pass', 'db_none']
127.0.0.1
3307
None
