How can I generate documentation without writing any docstrings?

Question

How can I generate documentation without writing a single line of docstring? I simply want to have an API reference page.

Because as I think, if there are type annotations in functions, then we don't need docstrings to describe them.

For example, one of my source code functions:

def sort_files_by_time(self, files: List[str], reverse: bool = False):
    files.sort(key=os.path.getmtime, reverse=reverse)
    return files

I expect it to generate API docs in HTML format. Like what I see in vscode function hint.
