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。

常见文档格式如下

[DEFAULT]ServerAliveInterval = 45Compression = yesCompressionLevel = 9ForwardX11 = yes [bitbucket.org]User = hg [topsecret.server.com]Port = 50022ForwardX11 = 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 parsertopsecret['ForwardX11'] = 'no'  # same hereconfig['DEFAULT']['ForwardX11'] = 'yes'with open('example.ini', 'w') as configfile:   config.write(configfile)　　

如何读取配置文件

>>> import configparser>>> config = configparser.ConfigParser()>>> config.sections()[]>>> config.read('example.ini')['example.ini']>>> config.sections()['bitbucket.org', 'topsecret.server.com']>>> 'bitbucket.org' in configTrue>>> 'bytebong.com' in configFalse>>> config['bitbucket.org']['User']'hg'>>> config['DEFAULT']['Compression']'yes'>>> topsecret = config['topsecret.server.com']>>> topsecret['ForwardX11']'no'>>> topsecret['Port']'50022'>>> for key in config['bitbucket.org']: print(key)...usercompressionlevelserveraliveintervalcompressionforwardx11>>> config['bitbucket.org']['ForwardX11']'yes'　　

configparser增删改查语法

[section1]k1 = v1k2: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"))　　

 

 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
