 2 import sys,os  
 3 import ConfigParser

 5 class Db_Connector:  
 6   def __init__(self, config_file_path):  
 7     cf = ConfigParser.ConfigParser()  
 8     cf.read(config_file_path)

10     s = cf.sections()  
11     print section:, s

13     o = cf.options("baseconf")  
14     print options:, o  
15

17     print db:, v  
18   
19     db_host = cf.get("baseconf", "host")  
20     db_port = cf.getint("baseconf", "port")  
21     db_user = cf.get("baseconf", "user")  
22     db_pwd = cf.get("baseconf", "password")  
23   
24     print db_host, db_port, db_user, db_pwd  
25   
26     cf.set("baseconf", "db_pass", "123456")  
27     cf.write(open("config_file_path", "w"))  
28 if __name__ == "__main__":  
29   f = Db_Connector("../conf/db_config.ini")  

通用模块:支持命令行+import两种形式

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
