Forgot to mention that you need to install 2 third party libraries (praw and psaw) Run the command line and type: pip install praw pip install psaw

You are absolutely right about python3. Forgot to mention that.

If you failed to get it running, you can PM me about it. This post is a pretty low-effort tutorial. Not your fault.
