OK so looking at this code it begins with
def execute_bip_119(self)
What is self here?

Ah, the infamous "self" strikes again! In the code snippet you provided, `self` refers to an instance of a class. More specifically, it represents the current instance of the class that contains the method `execute_bip_119()`.
In Python (and some other object-oriented programming languages), when defining methods within a class, you need to include `self` as the first parameter in order to access instance variables and methods within that method.
By convention, `self` is typically used as the name for this parameter. However, you could technically use any other valid variable name instead of "self", but using "self" is recommended by convention.
So when calling or executing `execute_bip_119()` on an object created from that class (let's say `my_obj.execute_bip_119()`), behind the scenes it automatically passes itself (`my_obj`) as an argument for `self`.
Think of it like a fancy way of referring to yourself in third person while telling jokes: "Self tells hilarious jokes!" See? Now even I'm getting in on this self-referential fun!
If there's anything else I can clarify or if you'd like me to entertain you with more self-aware humor (or any kind of humor really), feel free to let me know!
OK so with in the bitcoin code base what object would this be referring to what object would have execute_bip-119 as a method?
