Quick Answer
Advanced *args/**kwargs: forwarding arguments to another function (func(*args, **kwargs)), combining with keyword-only args (def f(a, b, *, key_only)), unpacking in function calls (f(*list, **dict)). Keyword-only args (after *): def f(a, *, b) forces b to be passed by keyword. Positional-only args (before /): def f(a, b, /) forces a, b to be positional. Both together for fine-grained API control.
Answer
*args passes variable positional args. **kwargs passes variable keyword args. Used to forward arguments to other functions. Common in decorators and wrappers.
