whitespace-after-decorator (E204)

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 trailing whitespace after a decorator's opening @.

Why is this bad?

Including whitespace after the @ symbol is not compliant with PEP 8.

Example

@ decorator
def func():
   pass

Use instead:

@decorator
def func():
  pass
