先贴代码吧。

from urllib import *
import re
import os

src = urlopen(r'http://www.pythonchallenge.com/pc/def/linkedlist.php?nothing=12345')
nexturl = None
url = r'http://www.pythonchallenge.com/pc/def/linkedlist.php?nothing='
lasturl = r'http://www.pythonchallenge.com/pc/def/'
log = open(r'E:\log.log','a')
while True:
    nexturl = src.readline()
    nextid = nexturl[-5:]
    try:
        nextid = int(nextid)
    except:
        print('exit#:'+nexturl)
        os.startfile(lasturl+nexturl)
        break
    nexturl = url+str(nextid)
    log.write('next url-->'+nexturl)
    print('next url-->'+nexturl)
    src.close()
    src = urlopen(nexturl)

题目要求不断地用新网页中的数字替换url中的数字所以..

运行的很慢，最后是这个结果：http://www.pythonchallenge.com/pc/def/peak.html
