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。
1 >>> import configparser 2 >>> config = configparser.ConfigParser() 3 >>> config.sections() 4 [] 5 >>> config.read(‘example.ini‘) 6 [‘example.ini‘] 7 >>> config.sections() 8 [‘bitbucket.org‘, ‘topsecret.server.com‘] 9 >>> ‘bitbucket.org‘ in config 10 True 11 >>> ‘bytebong.com‘ in config 12 False 13 >>> config[‘bitbucket.org‘][‘User‘] 14 ‘hg‘ 15 >>> config[‘DEFAULT‘][‘Compression‘] 16 ‘yes‘ 17 >>> topsecret = config[‘topsecret.server.com‘] 18 >>> topsecret[‘ForwardX11‘] 19 ‘no‘ 20 >>> topsecret[‘Port‘] 21 ‘50022‘ 22 >>> for key in config[‘bitbucket.org‘]: print(key) 23 ... 24 user 25 compressionlevel 26 serveraliveinterval 27 compression 28 forwardx11 29 >>> config[‘bitbucket.org‘][‘ForwardX11‘] 30 ‘yes‘
configparser增删改查语法
