Python之简洁ini读写 作者:xieaotian发表于2008-08-19 15:04:18
ini文件是常用的配置文件格式，当然，除了它之外，还有其他好多种，比如conf，xml等等。不过，今天就谈论ini罢了。
python对此提供了相应的模块，示例如下：
#coding=utf-8
import ConfigParser
def writeConfig(filename):
config = ConfigParser.ConfigParser()
# set db
section_name = 'db'
config.add_section( section_name )
config.set( section_name, 'dbname', 'MySQL')
config.set( section_name, 'host', '127.0.0.1')
config.set( section_name, 'port', '80')
config.set( section_name, 'password', '123456')
config.set( section_name, 'databasename', 'test')
# set app
section_name = 'app'
config.add_section( section_name )
config.set( section_name, 'loggerapp', '192.168.20.2')
config.set( section_name, 'reportapp', '192.168.20.3')
# write to file
config.write( open(filename, 'a') )
def updateConfig(filename, section, **keyv):
config = ConfigParser.ConfigParser()
config.read(filename)
[config.set(section, key, keyv[key]) for key in keyv if config.has_option(section, key)]
config.write( open(filename, 'r+') )
if __name__ == '__main__':
file_name = 'test.ini'
writeConfig(file_name)
updateConfig(file_name, 'app', reportapp = '192.168.100.100')
print "end__"
