I am using pylint on a script that uses the AWS CDK. In their source, they use a fully qualified @builtins.classmethod vs @classmethod to mark a class method and I am getting a no-value-for-parameter because pylint is expecting a parameter for the cls param. I am able to recreate it like so:

import pylint import builtins class Foo(): @classmethod def bar1(cls, text): print(text) @builtins.classmethod def bar2(cls, text): print(text) print(pylint.__version__) Foo.bar1("apple") Foo.bar2("pear") 

This runs on python 3.7.3 and the output is:

2.4.4 apple pear 

I am looking at this line of the class checker file where BUILTIN_DECORATORS = {"builtins.property", "builtins.classmethod"} is defined but then never used.

Current behavior

pylint warns of No value for argument 'text' in unbound method call pylint(no-value-for-parameter) when calling bar2 with only one parameter.

pylint also warns of a problem at the definition of bar2: Method should have "self" as first argument pylint(no-self-argument)

Expected behavior

Both methods should be interpreted as valid class methods and usage without passing a parameter for cls should not be interpreted as invalid usage

pylint --version output

2.4.4
