What it does

Checks for missing blank lines between methods of a class.

Why is this bad?

PEP 8 recommends exactly one blank line between methods of a class.

Example

class MyClass(object):
    def func1():
        pass
    def func2():
        pass

Use instead:

class MyClass(object):
    def func1():
        pass

    def func2():
        pass

Typing stub files (.pyi)

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