I am afraid to ask this. Might be silly. I've never seen @ signs in Python before. I am familiar with them from Java. Is there any relationship between the use of @ in Java annotations and its use in Python for decorators?

I think the best simple explanation I found of this was on this Stack Overflow Link
Python decorators are just syntactic sugar for passing a function to another function and replacing the first function with the result
Java annotations by themselves just store metadata, you must have something that inspects them to add behaviour.
