生成文件

import configparser

config = configparser.ConfigParser()
#在DEFAULT节点下添加，类似字典的key和value
config["DEFAULT"] = {'ServerAliveInterval': '45', 'Compression': 'yes', 'CompressionLevel': '9'}

config['bitbucket.org'] = {"alex":33}
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' #在在DEFAULT节点下添加key为'ForwardX11，value为yes的数据
with open('example.ini', 'w') as configfile:
config.write(configfile)

[DEFAULT] 创建文件的内容

#serveraliveinterval = 45
#compression = yes
#compressionlevel = 9
#forwardx11 = yes

#[bitbucket.org]
#alex = 33
#user = hg

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

configparser文件读取写入

import configparser

conf=configparser.ConfigParser()
conf.read("example.ini")
print(conf.sections())#打印节点（除了“DEFAULT”以外的节点）
print(conf["bitbucket.org"]["user"])
print(conf.defaults())#打印[DEFAULT]

#删除后，创建新文件写入
#sec = conf.remove_section('bitbucket.org')
#conf .write(open('exmple.cfg', "w"))

#删除后，覆盖原文件
#sec = conf.remove_section('bitbucket.org')
#conf .write(open('exmple.ini', "w"))
