Which describes non-executable explanations within code that help learners understand what a section does?
Correct Answer:
Documentation
Explanation:
Non-executable explanations within code are documentation. They appear as comments or docstrings that describe what a section does, its purpose, how to use it, and any important details or caveats. This guidance doesn’t run; it’s meant to help readers—students, future maintainers, or teammates—understand intent and behavior without having to infer everything from the code itself. For instance, a function’s docstring might outline its purpose, parameters, return value, and side effects, while inline comments can illuminate complex steps or design decisions. The other options describe runtime constructs or naming/style conventions rather than the explanatory notes embedded in code that aid understanding.
