Hi Very new to Python and Llama Index

from_defaults is what's called a classmethod in python. This means the function can be used before an object of that class is instansiated

In this case, it sets up a bunch of default settings, and returns an instansiated service context object. This way, you can modify a few defaults, and not have to worry about setting every kwarg

Thank you @Logan M this helped me a lot in understanding this term 🙂
