A developer is building a CLI tool that lists the documentation of all public functions in a module. The tool must display the docstring of each function when the user requests help. The developer wants to retrieve the docstring programmatically without importing the `inspect` module. Which approach should the developer use?

Use the `dir()` function on each function object.

Use the `__doc__` attribute of each function object.

Use the `__annotations__` attribute of each function object.

Use the `help()` function on each function object.

When might it be more appropriate to document types in a docstring rather than using annotations?

When the project does not use static type checking tools.

When the code must run on Python 2.

When the function has a simple return type.

When the function is private and not part of the public API.

For a class docstring, what additional information is commonly included after the summary line?

The names of all modules that import the class.

The complete source code of the class.

A description of the class's behavior, attributes, and usage examples.

A list of all methods and their signatures.

What does PEP 484 primarily define?

The conventions for writing docstrings.

The style guide for Python code.

The syntax for type hints in Python.

The rules for package distribution.
