PyYAML模块

Python也可以很容易的处理ymal文档格式，只不过需要安装一个模块，参考文档：http://pyyaml.org/wiki/PyYAMLDocumentation

常用模块之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

如果想用python生成一个这样的文档怎么做呢？

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)

写完了还可以再读出来哈。

 >>> import configparser

 >>> config = configparser.ConfigParser()

 >>> config.sections()

 []

 >>> config.read('example.ini')

 ['example.ini']

 >>> config.sections()

 ['bitbucket.org', 'topsecret.server.com']

 >>> 'bitbucket.org' in config

 True

 >>> 'bytebong.com' in config

 False

 >>> config['bitbucket.org']['User']

 'hg'

 >>> config['DEFAULT']['Compression']

 'yes'

 >>> topsecret = config['topsecret.server.com']

 >>> topsecret['ForwardX11']

 'no'

 >>> topsecret['Port']

 ''

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

 ...

 user

 compressionlevel

 serveraliveinterval

 compression

 forwardx11

 >>> config['bitbucket.org']['ForwardX11']

 'yes'

configparser增删改查语法

 [section1]

 k1 = v1

 k2:v2

 [section2]

 k1 = v1

 import ConfigParser

 config = ConfigParser.ConfigParser()

 config.read('i.cfg')

 # ########## 读 ##########

 #secs = config.sections()

 #print secs

 #options = config.options('group2')

 #print options

 #item_list = config.items('group2')

 #print item_list

 #val = config.get('group1','key')

 #val = config.getint('group1','key')

 # ########## 改写 ##########

 #sec = config.remove_section('group1')

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

 #sec = config.has_section('wupeiqi')

 #sec = config.add_section('wupeiqi')

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

 #config.set('group2','k1',11111)

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

 #config.remove_option('group2','age')

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