题目解析： 图片嵌入了第4题的图片，图片有很多cookie
所以需要先获取cookie,页面cookie信息 info ： you+should+have+followed+busynothing...
将第4题的后缀改为busynothing 然后在获取
代码如下：
#http://www.pythonchallenge.com/pc/return/romance.html username : huge password : file
#you+should+have+followed+busynothing...
#%B2hs%C0%9Fy%E3D%BC%8B%EB%B8i%98lu2o%5D%C9%A0

from http import cookies,cookiejar
import bz2
postdata= urllib.parse.urlencode({
'Username': 'huge',
'Password': 'file'
}).encode('utf-8')
