- A plenty of cookies. There is also a small picture on the lower left corner, remember it? It's the same photo as level 4. (I don't remember. Really.)
- Obviously, we should find out the cookies sent by level 4 webpage.
- See also: https://docs.python.org/2/library/cookielib.html
import cookielib, urllib2
cookies = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cookies))
webpage = opener.open("http://www.pythonchallenge.com/pc/def/linkedlist.php")
for c in cookies:
print c.name+" : "+c.value
- The result showes:
info : you+should+have+followed+busynothing...- Seems we have to follow the procedure solving level 4 ...the new procedure will end at the 116th iteration.
link = "http://www.pythonchallenge.com/pc/def/linkedlist.php?busynothing="
var = 12345
next_var = 0
cookie_list = []
for i in range(400):
new_link = link + str(var)
new_cookies = cookielib.CookieJar()
new_opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(new_cookies))
f = new_opener.open(new_link)
cookie_list.append(new_cookies)
urlcontent = f.read()
try:
next_var = re.findall("and the next busynothing is (\d+)", urlcontent)
var = int(''.join(next_var))
f.close()
except:
break
cookie_info = []
for i in cookie_list:
for j in i:
cookie_info.append(j.value)
print ''.join(cookie_info)
- The result is a string:BZh91AY%26SY%94%3A%E2I%21%19%80P%81%11%AFg%9E%A0+hE%3DM%B5%23%D0%D4%D1%E2%8D%06%A9%FA%26S%D4%D3%21%A1%EAi7h%9B%9A%2B%BF%60%22%C5WX%E1%ADL%80%E8V%3C%C6%A8%DBH%2632%18%A8x%01%08%21%8DS%0B%C8%AF%96KO%CA2%B0%F1%BD%1Du%A0%86%05%92s%B0%92%C4Bc%F1w%24S%85%09%09C%AE%24%90- Remember that? A string starts with BZH91AY? See level 8!
- Remember to use urllib.unquoat_plus() to replace %xx escapes.
- The result shows: is it the 26th already? call his father and inform him that "the flowers are on their way". he'll understand.
- 26th? Recall Mozart in level 15! Call his father? Google him! Mozart's father is Leopold. Before we call Leopold, we have to know his phone number. Again, remember level 13?
- We could obtain "555-VIOLIN", and they want us to visit http://www.pythonchallenge.com/pc/stuff/violin.php. "It's me. What do you want?" Leopold said.
- Now we have to let him know "the flowers are on their way".
cookies = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cookies))
webpage = opener.open("http://www.pythonchallenge.com/pc/def/linkedlist.php")
for c in cookies:
c.value = "the flowers are on their way"
new_webpage = opener.open("http://www.pythonchallenge.com/pc/stuff/violin.php")
print new_webpage.read()
- The returned webpage shows:
<html>
<head>
<title>it's me. what do you want?</title>
<link rel="stylesheet" type="text/css" href="../style.css">
</head>
<body>
<br><br>
<center><font color="gold">
<img src="leopold.jpg" border="0"/>
<br><br>
oh well, don't you dare to forget the balloons.</font>
</body>
</html>
- Finnaly, the answer is "balloons". What a huge work!
