blank-lines-after-function-or-class (E305)#

Derived from the pycodestyle linter.

Fix is always available.

This rule is unstable and in preview. The --preview flag is required for use.

What it does#

Checks for missing blank lines after the end of function or class.

Why is this bad?#

PEP 8 recommends using blank lines as follows:

  • Two blank lines are expected between functions and classes
  • One blank line is expected between methods of a class.


class User(object):
user = User()

Use instead:

class User(object):

user = User()

Typing stub files (.pyi)#

The typing style guide recommends to not use blank lines between statements except to group them. That's why this rule is not enabled in typing stub files.
