Python Encrypted Text

Question

I have been trying to decode a list of integers for the past few days but cannot figure out how with my basic knowledge of Python.
Could someone try to solve this and show me how they did it?
This has been driving my crazy since I started trying.
Here is the link to the encoded text
(Info on how it was encoded is in the link aswell.)
