样例文件
- 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(/proj/conf/example_conf)
[book] title:ConfigParser模块教程 author:大头爸爸 email:366500050@qq.com 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。
读取配置文件
- 示例文件: example.py
# -*- coding: utf-8 -*- import ConfigParser import string config=ConfigParser.ConfigParser() config.read(u'/proj/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
CONFIGPARSER模块教程 by 大头爸爸 (366500050@qq.com) 1024 ['book', 'size', 'other'] book title = ConfigParser模块教程 author = 大头爸爸 email = 366500050@qq.com time = 2012-09-20 22:04:55 size size = 1024 other blog = csdn.n
写入配置文件
- 示例
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
- 创建ConfigParser实例
config=ConfigParser.ConfigParser()
- 返回配置文件中节序列
config.sections()
- 返回某个项目中的所有键的序列
config=ConfigParser.ConfigParser() config.options(section)
- 返回section节中,option的键值
config=ConfigParser.ConfigParser() config.get(section,option)
- 添加一个配置文件节点(str)
config=ConfigParser.ConfigParser() config.add_section(str)
- 设置section节点中,键名为option的值(val)
config=ConfigParser.ConfigParser() config.set(section,option,val)
- 读取配置文件
config=ConfigParser.ConfigParser() config.read(filename)
- 写入配置文件
config=ConfigParser.ConfigParser() config.write(obj_file)
