python3 configparser模块

配置文件如下：

import configparser

conf = configparser.ConfigParser()
print(type(conf))   #conf是类
conf.read('config.ini')
sections = conf.sections()  #获取配置文件中所有sections，sections是列表
print(sections)
option = conf.options(conf.sections()[0]) #获取某个section下的所有选项或value，等价于 option = conf.options('logoninfo')
print(option)
#value = conf.get('logoninfo', 'addr')   #根据section和value获取key值,等价于value = conf.get(conf.sections()[0], conf.options(conf.sections()[0])[0])
print(value)
item = conf.items('logoninfo')
print(item)

运行结果如下：

<class 'configparser.ConfigParser'>
['logoninfo', 'logging', 'mysql']
['addr', 'passwd', 'popserver']
wangershazi
[('addr', 'wangershazi'), ('passwd', 'wangerxifu'), ('popserver', 'newmail')]
