import time,re,urllib2
t=time.time()
websiteurls={}
def scanpage(url):
 websiteurl=url
 t=time.time()
 n=0
 html=urllib2.urlopen(websiteurl).read()
 soup=BeautifulSoup(html)
 pageurls=[]
 Upageurls={}
 pageurls=soup.find_all("a",href=True)
 for links in pageurls:
  if websiteurl in links.get("href") and links.get("href") not in Upageurls and links.get("href") not in websiteurls:
   Upageurls[links.get("href")]=0
 for links in Upageurls.keys():
  try:
   urllib2.urlopen(links).getcode()
  except:
   print "connect failed"
  else:
   t2=time.time()
   Upageurls[links]=urllib2.urlopen(links).getcode()
   print n,
   print links,
   print Upageurls[links]
   t1=time.time()
   print t1-t2
  n+=1
 print ("total is "+repr(n)+" links")
 print time.time()-t
