**args

What this Python *args syntax question tests

This is an easy foundational question about Python's variable-length argument syntax. It assesses whether you understand how the *args parameter works, how it captures positional arguments, and what data structure it creates inside a function.

The question is practical: most Python developers encounter *args early, and quant shops expect you to read and write code that uses it fluently. You'll need to trace through a snippet, reason about argument unpacking, and predict the resulting output without running it—a skill that reinforces your mental model of Python's calling convention.

• Variadic positional arguments and tuple packing
• Argument unpacking and the * operator
• Function signatures and parameter binding
