python应用

域名过滤：从daminFile文件按行读取，将符合规则的域名行记录下来。

import osimport re#input the file pathdaminFile = raw_input('File path:\n')#result file pathresultFile = daminFile+'_rs.txt'fileRead = open(daminFile, 'r')fileWrite = open(resultFile, 'w')#set the ruleregex = ur'^[\w]{1,5}\.(com|net|org)$'#get each linefor eachLine in fileRead:print eachLineif re.match(regex, eachLine):fileWrite.write('%s' % eachLine)fileWrite.close()fileRead.close()

第一次将python用于实际需求：想注册一个域名，到最新过期的域名里挑，每天数十万的记录，人工挑选是不可能的，用python先挑选出长度5位以内，com/net/org 域名。

不算注释和空行，12行代码，python真的很省事。
