在用Python做开发的时候经常会用到数据库或者其他需要动态配置的东西，硬编码在里面每次去改会很麻烦。Python自带有读取配置文件的模块ConfigParser，使用起来非常方便。

ini文件
ini配置文件格式：

读取配置文件：

import ConfigParser
conf = ConfigParser.ConfigParser()
conf.read('dbconf.ini')       # 文件路径
name = conf.get("section1", "name") # 获取指定section 的option值
print name
sex = conf.get("section1", "sex")  # 获取section1 的sex值
print age
Copy after login

输出：

jhao
male
Copy after login


写入配置文件：

import ConfigParser
conf = ConfigParser.ConfigParser()
conf.read('dbconf.ini')

conf.set("section1", "name", "jhao104")    # 修改指定section 的option
conf.set("section1", "age", "21")       # 增加指定section 的option
conf.add_section("section3")         # 增加section
conf.set("section3", "site", "oschina.net")  # 给新增的section 写入option
conf.write(open('dbconf.ini', 'w'))
Copy after login

输出：
