1.基本的读取配置文件

-read(filename) 直接读取ini文件内容

-sections() 得到所有的section，并以列表的形式返回

-options(section) 得到该section的所有option

-items(section) 得到该section的所有键值对

-get(section,option) 得到section中option的值，返回为string类型

-getint(section,option) 得到section中option的值，返回为int类型，还有相应的getboolean()和getfloat() 函数。

 

2.基本的写入配置文件

-add_section(section) 添加一个新的section

 

3.基本示例

test.conf

[sec_a] 
a_key1 = 20 
a_key2 = 10 
  
[sec_b] 
b_key1 = 121 
b_key2 = b_value2 
b_key3 = $r 
b_key4 = 127.0.0.1 
parse_test_conf.py

import ConfigParser 
  
cf = ConfigParser.ConfigParser() 
  
#read config
cf.read("test.conf") 
  
# return all section
secs = cf.sections() 
print 'sections:', secs 
  
opts = cf.options("sec_a") 
print 'options:', opts 
  
kvs = cf.items("sec_a") 
print 'sec_a:', kvs 

#read by type
str_val = cf.get("sec_a", "a_key1") 
int_val = cf.getint("sec_a", "a_key2") 
  
print "value for sec_a's a_key1:", str_val 
print "value for sec_a's a_key2:", int_val 
  
#write config
#update value
cf.set("sec_b", "b_key3", "new-$r") 
#set a new value
cf.set("sec_b", "b_newkey", "new-value") 
#create a new section
cf.add_section('a_new_section') 
cf.set('a_new_section', 'new_key', 'new_value') 
  
#write back to configure file
cf.write(open("test.conf", "w"))
