What does PEP 8 recommend regarding the use of single versus double quotes for string literals?

Pick one style and use it consistently

Use single quotes for short strings and double for long ones

What is the primary benefit of using a trailing comma in a multi-line list or dictionary?

It is required by Python syntax

It makes future additions produce cleaner diffs

When must a Python source file include an explicit encoding declaration?

When the file is part of a package

When the file contains any non-ASCII characters

When the file uses a non-UTF-8 encoding

When the file is larger than 100 lines

Your team uses pylint with a custom configuration that enforces PEP 8 import grouping. A developer has a module that imports `json` (standard), `numpy` (third-party), and `config` (local). The developer also uses `from config import *` to bring in several names. Pylint reports errors for both import order and wildcard imports. Which change should the developer make?

Move the local import before the third-party import to satisfy the order check, and keep the wildcard import.

Combine all imports into a single group without blank lines to avoid the grouping error.

Replace the wildcard import with explicit imports of the needed names, and keep the three import groups in the correct order.

Keep the wildcard import but add `# pylint: disable=wildcard-import` to suppress the warning.
