python 的 ConfigParser 模块
configParser 模块用于操作特定格式的配置文件，该类配置文件可以包含一个或多个节（section），每个节可以有多个参数（键=值）。
样例配置文件（/home/colben/git/python/conf/example_conf）
[book] title:ConfigParser模块教程 author:大头爸爸 email:[email protected] time:2012-09-20 22:04:55 [size] size:1024 [other] blog:csdn.net
上面配置文件中用的是冒号，也可以用等号。
example.py文件
# -*- coding: utf-8 -*-
import ConfigParser
import string
config=ConfigParser.ConfigParser()
config.read(u'/home/colben/git/python/conf/example_conf')
print string.upper(config.get("book","title")),
print "by",config.get("book","author"),
print "("+config.get("book","email")+")"
print
print config.get("size","size")
print
print config.sections()
for section in config.sections():
print section
for option in config.options(section):
print " ",option,"=",config.get(section,option)
example.py文件执行结果

写入配置文件实例
import ConfigParser
import sys
config=ConfigParser.ConfigParser()
config.add_section("book")
config.set("book","title","这是标题")
config.set("book","author","大头爸爸")
config.add_section("size")
config.set("size","size",1024)
config.write(sys.stdout)
执行结果
[book] title = 这是标题 author = 大头爸爸 [size] size = 1024
ConfigParser方法
#1、创建ConfigParser实例 config=ConfigParser.ConfigParser() #2、返回配置文件中节序列 config.sections() #3、返回某个项目中的所有键的序列 config.options(section) #4、返回section节中，option的键值 config.get(section,option) #5、添加一个配置文件节点(str) config.add_section(str) #6、设置section节点中，键名为option的值(val) config.set(section,option,val) #7、读取配置文件 config.read(filename) #8、写入配置文件 config.write(obj_file)
