ClientException about practical-docker-with-python

[jadm333]

This is because the code is written for a deprecated API.
You have two choices in order to make this to work.

1. Modify the reddit.py script. You need to change a couple of function name and add a client_id and a client_secret. This two tokens are generated in the reddit app page (https://github.com/reddit-archive/reddit/wiki/OAuth2). This is the one I used.
2. This solutions it's the easiest one. You can copy the reddit.py script from another folder of the repo, because that problem i'ts already fixed. I notice this when I advance the book.

Hope it helps!
PD: I attach the script I used.
