Here's a good function header given the following:
I wrote the below code

    class MockClassifier(BaseEstimator, ClassifierMixin, ):
        'Mock    Classifier    to    check    that    sample_weight    is    received    as    kwargs'
        def fit(self, X, y, *args, **sample_weight):
            assert_true(('sample_weight' in sample_weight))
    clf = MockClassifier()
    eclf = VotingClassifier(estimators=[('mock', clf)], voting='soft')
    eclf.fit(X, y, sample_weight=np.ones((len(y),)))

What's a good function header?
