读取配置文件（configparser，.ini文件）

使用configparser来读取配置信息config.ini

读取的信息（config.ini）如下：

[baseconf]
host=127.0.0.1
port=3306
user=root
password=root
db_name=evaluting_sys
[concurrent]
processor=20

　　

读取配置文件的代码（readconfig.py）：

# -*- coding:utf-8 -*-
import sys,os
import ConfigParser

class ReadConfig:
    def __init__(self, config_file_path):
        cf = ConfigParser.ConfigParser()
        cf.read(config_file_path)
        s = cf.sections()
        print 'section:', s
        o = cf.options("baseconf")
        print 'options:', o
        v = cf.items("baseconf")
        print 'db:', v
        db_host = cf.get("baseconf", "host")
        db_port = cf.getint("baseconf", "port")
        db_user = cf.get("baseconf", "user")
        db_pwd = cf.get("baseconf", "password")
        print db_host, db_port, db_user, db_pwd
        cf.set("baseconf", "db_pass", "123456")
        cf.write(open("config_file_path", "w"))


if __name__ == "__main__":
    f = ReadConfig("../conf/db_config.ini")
