Could you write pocket.shonenmagazine.com ripper for python 3.6??

a few touches here and there, and boom, a working python3 script

Not work. Can you fix?

Here's a newer version for python 3: https://gist.github.com/Nominom/634f27db499c04ae08f3962ce6cd9a4d
(Working as of 12/2020)

It's working. Thank you so much.
