使用 ConfigParser 读取和修改INI配置文件

    在程序中使用配置文件来灵活的配置一些参数是一件很常见的事情，配置文件的解析或修改并不复杂，在python里更是如此，在官方发布的库中就包含有做这件事情的库，那就是ConfigParser，ConfigParser模块解析的配置文件的格式类似ini的配置文件格式，就是文件由多个section构成，每个section下又有多个配置项，下面使用一个具体脚本来说明这个模块的使用方法:

chconfig.py

import sys
import ConfigParser

def getinfo(COLUMN,ITEM):
    conf=ConfigParser.ConfigParser()
    CONFIGNAME = 'game.ini'
    if os.path.isfile(CONFIGNAME):
        conf.read(CONFIGNAME)
        conf.sections()
        try:
            return conf.get(COLUMN,ITEM)
        except ConfigParser.NoOptionError, e:
            print 'Wanning:',e
            sys.exit()
    else:
        print 'Wanning: "%s" is not exists, you must appoint the absolute path of config file with -p or -c.'%(CONFIGNAME)
        sys.exit()


def setinfo(COLUMN,ITEM,VALUE):
    conf=ConfigParser.ConfigParser()
    CONFIGNAME = 'game.ini'
    if os.path.isfile(CONFIGNAME):
        conf.read(CONFIGNAME)
        conf.sections()
        try:
            conf.set(COLUMN,ITEM,VALUE)
            conf.write(open(CONFIGNAME, 'w'))
        except ConfigParser.NoOptionError, e:
            print 'Wanning:',e
            sys.exit()
    else:
        print 'Wanning: "%s" is not exists, you must appoint the absolute path of config file with -p or -c.'%(CONFIGNAME)
        sys.exit()
        

if __name__ == '__main__':
    print getinfo('Account','DBName')
    setinfo('Account','DBName','GameDB')
    print getinfo('Account','DBName')


 

 

game.ini

[Account]
username = test01
servername = 192.168.0.1
password = 123456
dbname = AccountDB

[Database]
username = test02
servername = 192.168.0.2
password = 123456
dbname = GameDB
