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

    @classmethod
    def setup_class(cls):
        _skip_if_no_openpyxl()
        import openpyxl
        ver = openpyxl.__version__
        if (not ((LooseVersion(ver) >= LooseVersion('2.0.0')) and (LooseVersion(ver) < LooseVersion('2.2.0')))):
            pytest.skip(('openpyxl    %s    >=    2.2' % str(ver)))
    cls.setup_class = setup_class
    return cls

What's a good function header?
