ends-in-punctuation (D415)#

Derived from the pydocstyle linter.

Fix is always available.

What it does#

Checks for docstrings in which the first line does not end in a punctuation mark, such as a period, question mark, or exclamation point.

Why is this bad?#

The first line of a docstring should end with a period, question mark, or exclamation point, for grammatical correctness and consistency.

This rule may not apply to all projects; its applicability is a matter of convention. By default, this rule is enabled when using the google convention, and disabled when using the numpy and pep257 conventions.

Example#

def average(values: list[float]) -> float:
    """Return the mean of the given values"""

Use instead:

def average(values: list[float]) -> float:
    """Return the mean of the given values."""
