Why is this an issue?
Class methods that don’t access instance data can and should be static because they yield more performant code.
To implement a static method in Python one should use either @classmethod or @staticmethod. A class method receives the
class as implicit first argument, just like an instance method receives the instance. A static method does not receive an implicit first argument.
Noncompliant code example
class Utilities:
    def do_the_thing(self, arg1, arg2, ...):  # Noncompliant
        #...

Compliant solution
class Utilities:
    @classmethod
    def do_the_thing(cls, arg1, arg2, ...):
        #...

or
class Utilities:
    @staticmethod
    def do_the_thing(arg1, arg2, ...):
        #...

Exceptions
Methods which raise or may raise a NotImplementedError are ignored.
