获取web.py上面的示例code

import requests
import re
import os.path#取得文件名和内容对应字典
def getCode(url):
pattern=re.compile(r'<h\d>([^<]+)?</h\d>\n*<pre><code>[^<]*</code>{1}?',re.S)
dic={}
r=requests.get(url)
if r.status_code==200:
for g in re.finditer(pattern,r.text):
dic[g.group(1)]=g.group(0)
return dic#输出到文件中
def saveFile(saveDir,dic):
if not os.path.isdir(saveDir):
os.makedirs(saveDir)
for key in dic:
print key,dic[key]
#
outPath=saveDir
fileName=key
rIndex=key.rfind("/")

if not os.path.isdir(outPath):
os.makedirs(outPath)
outFile=open(outPath+"\\"+fileName,'w')
beginIndex=dic[key].find("<code>")
endIndex=dic[key].find("</code>")
if beginIndex==-1 or endIndex==-1:
print "<code> have not"
return
subs=dic[key][beginIndex+6:endIndex]
outFile.write(subs)
outFile.close()url1='http://webpy.org/skeleton/0.3'
url2='http://webpy.org/src/blog/0.3'

url4='http://webpy.org/src/wiki/0.3'urls=(url1,url2,url3,url4)for url in urls:

#相对目录不变
