　　写入配置文件：
　　import ConfigParser, os #引用的模块：config = ConfigParser.RawConfigParser()# When adding sections or items, add them in the reverse order of# how you want them to be displayed in the actual file.# In addition, please note that using RawConfigParser's and the raw# mode of ConfigParser's respective set functions, you can assign# non-string values to keys internally, but will receive an error# when attempting to write to a file or when you get it in non-raw# mode. SafeConfigParser does not allow such assignments to take place.config.add_section('Section1')config.set('Section1', 'int', '15')config.set('Section1', 'bool', 'true')config.set('Section1', 'float', '3.1415')config.set('Section1', 'baz', 'fun')config.set('Section1', 'bar', 'Python')config.set('Section1', 'foo', '%(bar)s is %(baz)s!')# Writing our configuration file to 'example.cfg'with open('example.cfg', 'wb') as configfile:config.write(configfile)
　　
读入这个配置文件：
import ConfigParserconfig = ConfigParser.RawConfigParser()config.read('example.cfg')# getfloat() raises an exception if the value is not a float# getint() and getboolean() also do this for their respective typesfloat = config.getfloat('Section1', 'float')int = config.getint('Section1', 'int')print float + int# Notice that the next output does not interpolate '%(bar)s' or '%(baz)s'.# This is because we are using a RawConfigParser().if config.getboolean('Section1', 'bool'):print config.get('Section1', 'foo')
