    -read(filename)                  直接读取文件内容-sections()                      得到所有的section，并以列表的形式返回-options(section)                得到该section的所有option-items(section)                  得到该section的所有键值对-get(section,option)             得到section中option的值，返回为string类型-getint(section,option)          得到section中option的值，返回为int类型，还有相应的getboolean()和getfloat() 函数。

    -add_section(section) 添加一个新的section-set( section, option, value) 对section中的option进行设置，需要调用write将内容写入配置文件。

#  实例化configParser对象
cf = configparser.ConfigParser()

#  读取config.ini文件
cf.read(config.ini)

以get为例，示例代码如下：#  定义方法，获取config分组下指定name的值
def getConfigValue(self, name):value = self.cf.get("config", name)return value
#  定义方法，获取cmd分组下指定name的值
def getCmdValue(self, name):value = self.cf.get("cmd", name)return value

#  定义方法，修改config分组下指定name的值value
def setConfigValue(self, name, value):cfg = self.cf.set("config", name, value)fp = open(r'config.ini', 'w')cfg.write(fp)

#  不区分大小写,以下两个等价，都获取appActivity的值
self.cf.get("config", "appActivity")
self.cf.get("config", "APPACTIVITY")

#  以下取得的值都是等价的为ture
