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 os
import re

#input the file path
daminFile = raw_input('File path:\n')
#result file path
resultFile = daminFile+'_rs.txt'

fileRead = open(daminFile, 'r')
fileWrite = open(resultFile, 'w')

#set the rule
regex = ur'^[\w]{1,5}\.(com|net|org)$'

#get each line
for eachLine in fileRead:
	print eachLine
	if 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。

去除项目目中中.svn文件：

import os,sys,stat,shutil

dirPath = ''

def walk(path):
	for fileobj in os.listdir(path):
		if fileobj == '.svn':
			shutil.rmtree(os.path.join(path, fileobj))
		else:
			filepath = path+'//'+fileobj
			isDir = os.path.isdir(filepath)
			if isDir:
				print filepath
				walk(filepath)

def getInput():
	dirPath = raw_input('Enter the dir path(eg:"e:/test"):\n')
	if os.path.isdir(dirPath):
		walk(dirPath)
	else:
		print 'there is not a directory named ' + dirPath
		getInput()

if __name__=='__main__':
	getInput()
