利用configparser生成一个文档

比如我想生成一个文档为：

[DEFAULT]
serveraliveinterval = 45
compression = yes
compressionlevel = 9
forwardx11 = yes

[bitbucket.org]
user = hg

[topsecret.server.com]
host port = 50022
forwardx11 = no

可以利用configparser来生成：

import configparser

config = configparser.ConfigParser()
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)
