blank-line-after-last-section (D413)
Derived from the pydocstyle linter.
Fix is always available.
What it does
Checks for missing blank lines after the last section of a multiline docstring.
Why is this bad?
This rule enforces a consistent style for multiline docstrings.
Multiline docstrings are typically composed of a summary line, followed by a blank line, followed by a series of sections, each with a section header and a section body.
This rule may not apply to all projects; its applicability is a matter of
convention. By default, the rule is disabled when using the google,
numpy, and pep257 conventions.
Example
def calculate_speed(distance: float, time: float) -> float:
"""Calculate speed as distance divided by time.
Parameters
----------
distance : float
Distance traveled.
time : float
Time spent traveling.
Returns
-------
float
Speed as distance divided by time.
Raises
------
FasterThanLightError
If speed is greater than the speed of light.

try:
return distance / time
