Blank lines found after function decorator (E304)

There should be no blank lines between a function decorator and the function it is decorating.

Anti-pattern

In this example, the property decorator has a space between it and the name method. The space should be removed.

class User(object):

    @property

    def name(self):
        pass

Best practice

class User(object):

    @property
    def name(self):
        pass
