Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Just define the function with many arguments; it is perfectly fine.
Why it's wrong here
This leads to 'code smell' and high cognitive load.
- ✗
Use a single argument dictionary.
Why it's wrong here
This loses type safety and IDE autocompletion benefits.
- ✗
Use *args and **kwargs for everything.
Why it's wrong here
This makes the API opaque and hard to debug.
- ✓
Group related parameters into a dataclass or object.
Why this is correct
This improves readability and maintainability.
