# 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
except ZeroDivisionError as exc:
raise FasterThanLightError from exc
```

Use instead:

```
