Question

You maintain a Python order-processing service. A single function `create_order(customer_id, product_id, quantity, discount, shipping_address, billing_address, gift_wrap, priority, coupon_code, notes)` has grown to ten positional parameters, and callers frequently mix up argument order, causing subtle bugs. You want Copilot to help improve maintainability without changing the function's external behavior for existing tests. Which approach best uses Copilot for this refactoring?

Accepted Answer

Select the function and prompt Copilot Chat to introduce a parameter object (e.g., a dataclass) that groups the related fields, then update call sites and verify the existing tests still pass.

Answer

Ask Copilot to delete the least-used parameters so the signature is shorter and easier to call.

Answer

Ask Copilot to convert all parameters to a single `*args` tuple so callers can pass values in any quantity.

Answer

Ask Copilot to rewrite the function to read the values from global variables instead of parameters.
