python 配置文件 ConfigParser模块

ConfigParser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。

来看一个好多软件的常见文档格式如下

[DEFAULT]
ServerAliveInterval = 45
Compression = yes
CompressionLevel = 9
ForwardX11 = yes

[bitbucket.org]
User = hg

[topsecret.server.com]
Port = 50022
ForwardX11 = no

python生成配置文件

import configparser

config = configparser.ConfigParser()
config["DEFAULT"] = {'ServerAliveInterval': '',
                      'Compression': 'yes',
                     'CompressionLevel': ''}

config['bitbucket.org'] = {}
config['bitbucket.org']['User'] = 'hg'
config['topsecret.server.com'] = {}
topsecret = config['topsecret.server.com']
topsecret['Host Port'] = ''     # mutates the parser
topsecret['ForwardX11'] = 'no'  # same here
config['DEFAULT']['ForwardX11'] = 'yes'
with open('example.ini', 'w') as configfile:
   config.write(configfile)

读取配置文件信息

#!/usr/bin/env python3
# -*- coding:utf-8 -*-

import configparser

config = configparser.ConfigParser()
config.sections()

config.read('example')

config.sections()

for i in config.keys():
    print(i, end=' ')
print("=" * 50)
print(config.keys())

print(config['bitbucket.org']['User'])

print(config['DEFAULT']['Compression'])

topsecret = config['topsecret.server.com']
print(topsecret['ForwardX11'])
print(topsecret['Port'])

for key in config['bitbucket.org']:
    print(key)

print(config['bitbucket.org']['ForwardX11'])

configparser增删改查语法
