页面提示信息：pronounce it

查看源码获得提示：peak hell sounds familiar ? 

有个src：http://www.pythonchallenge.com/pc/def/banner.p

使用pickle处理banner.p

from urllib.request import urlopen
import pickle

url = "http://www.pythonchallenge.com/pc/def/banner.p"
html = urlopen(url)

for line in pickle.load(html):
    for info in line:
        for i in range(info[1]):
            print(info[0],end="")
    print("")
