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）

 7 [size]  
 8 size:1024

上面配置文件中用的是冒号，也可以用等号。

example.py文件

 1 # -*- coding: utf-8 -*-  
 2 import ConfigParser  
 3 import string  
 4 config=ConfigParser.ConfigParser()  
 5 config.read(u'd:/百度网盘/android/Python/python_example/sample.ini')  
 6 print string.upper(config.get("book","title")),  
 7 print "by",config.get("book","author"),  
 8 print "("+config.get("book","email")+")"  
 9 print  
10 print config.get("size","size")  
11 print  
12 print config.sections()  
13   
14 for section in config.sections():  
15     print section  
16     for option in config.options(section):  
17         print " ",option,"=",config.get(section,option)

example.py文件执行结果

写入配置文件实例

1 import ConfigParser  
2 import sys  
3 config=ConfigParser.ConfigParser()  
4 config.add_section("book")  
5 config.set("book","title","这是标题")  
6 config.set("book","author","大头爸爸")  
7 config.add_section("size")  
8 config.set("size","size",1024)  
9 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)
