柳树舒展开了黄绿嫩叶的枝条，在微微的春风中轻柔地拂动，就像一群群身着绿装的仙女在翩翩起舞。夹在柳树中间的桃树也开出了鲜艳的花朵，绿的柳，红的花，真是美极了！

很类似java的properties文件xml文件


db_config.ini
[baseconf]
host=127.0.0.1
port=3306
user=root
password=root
db_name=evaluting_sys
[concurrent]
processor=20

对应的python代码


#!/usr/bin/python
# -*- coding:utf-8 -*-
#author: lingyue.wkl
#desc: use to db ops
#---------------------

import sys,os
import ConfigParser
class Db_Connector:
 def __init__(self, config_file_path):
 cf = ConfigParser.ConfigParser()
 cf.read(config_file_path)
 s = cf.sections()
 print 'section:', s
 o = cf.options("baseconf")
 print 'options:', o
 v = cf.items("baseconf")
 print 'db:', v
 db_host = cf.get("baseconf", "host")
 db_port = cf.getint("baseconf", "port")
 db_user = cf.get("baseconf", "user")
 db_pwd = cf.get("baseconf", "password")
 print db_host, db_port, db_user, db_pwd
 cf.set("baseconf", "db_pass", "123456")
 cf.write(open("config_file_path", "w"))
if __name__ == "__main__":
 f = Db_Connector("../conf/db_config.ini")

得到结果：


section: ['concurrent', 'baseconf']
options: ['host', 'db_name', 'user', 'password', 'port']
db: [('host', '127.0.0.1'), ('db_name', 'evaluting_sys'), ('user', 'root'), ('password', 'root'), ('port', '3306')]
127.0.0.1 3306 root root

通用模块：支持命令行+import两种形式
ini_op.py


#!/usr/bin/python
# -*- coding:utf-8 -*-
#author: lingyue.wkl
#desc: use to read ini

#2012-02-18 created

import sys,os,time
import ConfigParser

class Config:
 def __init__(self, path):
 self.path = path
 self.cf = ConfigParser.ConfigParser()
 self.cf.read(self.path)
 def get(self, field, key):
 result = ""
 try:
 result = self.cf.get(field, key)
 except:
 result = ""
 return result
 def set(self, filed, key, value):
 try:
 self.cf.set(field, key, value)
 cf.write(open(self.path,'w'))
 except:
 return False
 return True
def read_config(config_file_path, field, key): 
 cf = ConfigParser.ConfigParser()
 try:
 cf.read(config_file_path)
 result = cf.get(field, key)
 except:
 sys.exit(1)
 return result
def write_config(config_file_path, field, key, value):
 cf = ConfigParser.ConfigParser()
 try:
 cf.read(config_file_path)
 cf.set(field, key, value)
 cf.write(open(config_file_path,'w'))
 except:
 sys.exit(1)
 return True
if __name__ == "__main__":
 if len(sys.argv) < 4:
 sys.exit(1)
 config_file_path = sys.argv[1] 
 field = sys.argv[2]
 key = sys.argv[3]
 if len(sys.argv) == 4:
 print read_config(config_file_path, field, key)
 else:
 value = sys.argv[4]
 write_config(config_file_path, field, key, value)

第二个示例


import os
import ConfigParser
def main():
 cp = ConfigParser.ConfigParser() 
 cf = open(u"in.ini")
 cp.readfp(cf)
 secs = cp.sections()
 print cp.sections()
 for sec in secs:
 opts = cp.options(sec)
 for opt in opts:
 val = cp.get(sec, opt)
 val += "test....."
 cp.set(sec, opt, val)
 cp.write(open("out.ini", "w"))
if __name__ == '__main__':
 main()
