python3-flake8-class-newline 1.6.0-2 (amd64 binary) in ubuntu jammy

 PEP8 recommends surrounding every class method with a single blank line. See
 https://www.python.org/dev/peps/pep-0008/#blank-lines However flake8 is
 ambiguous about the first method having a blank line above it.
 .
 This plugin was made to enforce the blank line just after the method
 declaration.
