import ConfigParser

def read(rConfFileName):
    init = ConfigParser.ConfigParser()         # 初始化实例
    init.read("%s"%rConfFileName)              # 读取配置文件

    sections = init.sections()                 # 获取所有sections
    print "sections : ",sections               # 输出列表

    options = init.options("auther")           # 获取指定section 的options
    print "options : ",options                 # 输出列表，指定section里的所有key

    items = init.items("information")          # 获取指定section 的配置信息
    print "items : ",items

    information_blogaddress = init.get("information", "blogaddress") # 读取指定section中指定option 信息
    print "information_blogaddress : ",information_blogaddress

    auther_age = init.getint("auther", "age")  #获取的option为整型
    print "auther_age : ",auther_age

def write(wConfFileName):
    init = ConfigParser.ConfigParser()          # 初始化实例
    init.add_section('time')                    # 添加一个section
    init.set("time", "today", "sunday")         # 设置某个option 的值
    init.write(open("%s"%wConfFileName, "w"))   # 写入“w”，追加“a”

    init.add_section('times')                    # 添加一个要删除的section
    init.set("times", "tomorrowss", "mondays")   # 该项后面要删除
    init.remove_option('times','tomorrowss')     # 移除option，打开文件看一下，在把下面的注释（#）去掉
    #init.remove_section('times')                 # 移除section 
    init.write(open("%s"%wConfFileName, "w"))    # 写入“w”，追加“a”

if __name__ == "__main__":
    read('rconf.ini')
    write('wconf.ini')                            # 自动创建wconf.ini

read输出：

sections :  ['auther', 'information']
options :  ['name', 'gender', 'age']
items :  [('blogaddress', 'blog.csdn.net/z_johnny')]
information_blogaddress :  blog.csdn.net/z_johnny
auther_age :  24
