python 的配置文件模块

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 ConfigParser config = 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 types float = 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')
