01 import urllib2
02 import re
03 str = 'http://www.pythonchallenge.com/pc/def/linkedlist.php?nothing=%s'
04 num = 12345
05
06 while num:
07 cont = urllib2.urlopen(str % num).read()
08 result = re.compile('the next nothing is (\d+)').findall(cont)
09 print cont
10 if len(result) != 1:
11 print 'Finshed'
12 break
13 num = result[0]
