很类似java的properties文件

xml文件

复制代码 代码如下:
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

复制代码 代码如下:
#!/usr/bin/python
# -*- coding:utf-8 -*-

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：

复制代码 代码如下:
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

第二个示例

复制代码 代码如下:
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()
