surrounding-whitespace (D210)

Derived from the pydocstyle linter.

Fix is sometimes available.

What it does

Checks for surrounding whitespace in docstrings.

Remove surrounding whitespace from the docstring, for consistency.

def factorial(n: int) -> int:
    """ Return the factorial of n. """

Use instead:

def factorial(n: int) -> int:
    """Return the factorial of n."""
