configparse模块

创建config文件：

import configparser

config=configparser.ConfigParser()              #config={}
#----调用configparser下的一个类去实例化一个对象，命名为config

config["DEFAULT"]={'ServerAliveInterval':"45",
                   'Compression':'yes',
                   'CompressionLevel':'9'}

config['bitbucket.org']={}
config['bitbucket.org']['User']='hg'

config['topsecret.server.com']={}
topsecret=config['topsecret.server.com']
topsecret['Host Port']='50022'
topsecret['ForwardXll']='no'

with open('confile','w') as configfile:
    config.write(configfile)

运行结果：

#confile

[DEFAULT]
serveraliveinterval = 45
compression = yes
compressionlevel = 9

[bitbucket.org]
user = hg

[topsecret.server.com]
host port = 50022
forwardxll = no

config.add_section("yuan")                   #添加块              
config.set("yuan","name","alex")            #添加键值对

config.write(open("i.cfg","w"))                                

运行结果：
