hi all,
i am trying to write python script which takes a url and opens that page
...then i am trying to grab all  the links present in that page and want
to put that links in a data structure.....
now my problem is that how do i use a data structure and how should i put
this links into that.....

following is my code :

#!/usr/local/bin/python

import sys
import urllib
import re

url = sys.argv[1]

try:
    fp = urllib.urlopen(url)
except IOError:
    fp = ('*** ERROR: invalid URL ***')

done = 0


while not done:

      line = fp.readline()

      if line != "":

	   link = re.findall('href="(.*?)"', line)

	   if len(link) != 0:

	        for get_link in link:

		     print url + " " + "->" + " " + get_link

      else:
           done=1

fp.close()
