写入配置文件：

import ConfigParser, os<br /> #引用的模块：<br /> config = ConfigParser.RawConfigParser()</p> <p># When adding sections or items, add them in the reverse order of<br /> # how you want them to be displayed in the actual file.<br /> # In addition, please note that using RawConfigParser's and the raw<br /> # mode of ConfigParser's respective set functions, you can assign<br /> # non-string values to keys internally, but will receive an error<br /> # when attempting to write to a file or when you get it in non-raw<br /> # mode. SafeConfigParser does not allow such assignments to take place.<br /> config.add_section('Section1')<br /> config.set('Section1', 'int', '15')<br /> config.set('Section1', 'bool', 'true')<br /> config.set('Section1', 'float', '3.1415')<br /> config.set('Section1', 'baz', 'fun')<br /> config.set('Section1', 'bar', 'Python')<br /> config.set('Section1', 'foo', '%(bar)s is %(baz)s!')</p> <p># Writing our configuration file to 'example.cfg'<br /> with open('example.cfg', 'wb') as configfile:<br /> config.write(configfile)<br />

读入这个配置文件：
import ConfigParser</p> <p>config = ConfigParser.RawConfigParser()<br /> config.read('example.cfg')</p> <p># getfloat() raises an exception if the value is not a float<br /> # getint() and getboolean() also do this for their respective types<br /> float = config.getfloat('Section1', 'float')<br /> int = config.getint('Section1', 'int')<br /> print float + int</p> <p># Notice that the next output does not interpolate '%(bar)s' or '%(baz)s'.<br /> # This is because we are using a RawConfigParser().<br /> if config.getboolean('Section1', 'bool'):<br /> print config.get('Section1', 'foo')<br />
