Your team is debating whether to add a new feature that would make code more concise but harder to read. A senior engineer quotes a principle from PEP 20 to argue against it. Which aphorism from the Zen of Python best supports the argument that readability should take priority over brevity?

There should be one-- and preferably only one --obvious way to do it.

A developer is writing a function that returns either a list of results or `None` if no results are found. A colleague suggests that 'Explicit is better than implicit' from PEP 20 applies. What change should be made?

Return an empty list instead of `None` when there are no results.

Raise an exception when there are no results.

Keep returning `None` because it is simpler.

Add a comment explaining that `None` means no results.
