blank-lines-between-header-and-content (D412)#
Derived from the pydocstyle linter.
Fix is always available.
What it does#
Checks for docstring sections that contain blank lines between a section header and a section body.
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. There should be no blank lines between a section header and a section body.
Example#
def calculate_speed(distance: float, time: float) -> float:
"""Calculate speed as distance divided by time.
Args:
distance: Distance traveled.
time: Time spent traveling.
Returns:
Speed as distance divided by time.
Raises:
FasterThanLightError: If speed is greater than the speed of light.

try:
return distance / time
