Which design best makes a function for counting passing scores reusable and easy to test?
- A
A function accepts scores and returns the count, while separate code handles input and printing
- B

Select all the practices that improve the clarity and maintainability of Python code.
- A
Use descriptive names such as passing_scores
- B
Prefer early returns when they avoid deep nesting
- C
Use except Exception: pass to hide unexpected failures
- D
Write comments that explain intent or non-obvious decisions
12
True or false
