So, if I was to boil it down, its like "Hey, use Python, but with a different writing style you are used to."?
It would genuinely be worth your while to watch the SICP lectures with Gerry Sussman and Hal Abelson [1] to get an inkling of an idea of what "your program is just more data" can mean. Lisp is more about brining the language up to the level of the problem than bringing the problem down to the level of the language, and it's difficult to appreciate what that means until you've seen it. By the time you get to the end of lecture 3B, it should click.

Because I'm still a bit confused at what Lisp is!
You're in for a treat!
