[PythonChallenge]第4关

http://www.pythonchallenge.com/pc/def/linkedlist.php

网页的title是follow the chain

网页的注释中有提示, 需要修改nothing后面的数字少于400次

每修改一次都会在页面中显示下一次的数字, 重复操作即可

代码如下

import reimport urllib.requestfront_url = "http://www.pythonchallenge.com/pc/def/linkedlist.php?nothing="num = "12345"for i in range(1, 400):url = front_url + numpage = urllib.request.urlopen(url)text_bytes = page.read()page.close()text = text_bytes.decode("utf8")result = re.findall(r"nothing is ([0-9]*)", text)if result == []:num = str(int(num) // 2)print(i, num, text)else:num = ''.join(result)print(i, num)

中间有一次会提示将数字除以2

最后结果为66831

页面为peak.html

输入地址栏即可进入下一关
