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

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()
