#该模块用于生成和修改常见配置文档，当前模块的名称在 python 3.x 版本中变更为 configparser；python2中为ConfigParser
#来看一个好多软件常见文档格式如下：
# [DEFAULT]
# ServerAliveInterval = 45
# Compression = yes
# CompressionLevel = 9
# ForwardX11 = yes
#
# [bitbucket.org]
# User = hg
#
# [topsecret.server.com]
# Port = 50022
# ForwardX11 = no

#用python生成该种类型的文档
import configparser
config = configparser.ConfigParser()#用于生成一个configparser对象
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'  # mutates the parser
topsecret['ForwardX11'] = 'no'  # same here
config['DEFAULT']['ForwardX11'] = 'yes'
with open('example.ini', 'w') as configfile:
    config.write(configfile)


#读取该模块
conf = configparser.ConfigParser()
conf.read("example.ini")
print(conf.default_section)#打印默认default标签
print(conf.sections())
print(conf["topsecret.server.com"]["forwardx11"])
#删除某个节点
sec = conf.remove_section("topsecret.server.com")
conf.write(open("example2.cfg","w"))
