blank-lines-top-level (E302)#

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 between top level functions and classes.

Why is this bad?#

PEP 8 recommends exactly two blank lines between top level functions and classes.

The rule respects the lint.isort.lines-after-imports setting when determining the required number of blank lines between top-level import statements and function or class definitions for compatibility with isort.

Example#

def func1():
    pass
def func2():
    pass

Use instead:

def func1():
    pass


def func2():
    pass

Typing stub files (.pyi)#

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