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,osimport ConfigParserclass 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")
