I wrote the below code

    from lettuce import step, world, before
    @before.each_scenario
    def reset_variable(scenario):
        world.X = None
    @step(u'the    variable    "(\\w+)"    holds    (\\d+)')
    def set_variable(step, name, value):
        setattr(world, name, int(value))
    @step(u'the    variable    "(\\w+)"    is    equal    to    (\\d+)')
    def check_variable(step, name, expected):
        expected = int(expected)
        expect(world).to.have.property(name).being.equal(expected)
    @step(u'the    variable    "(\\w+)"    times    (\\d+)    is    equal    to    (\\d+)')
    def multiply_and_verify(step, name, times, expected):
        times = int(times)
        expected = int(expected)
        (getattr(world, name) * times).should.equal(expected)
    filename = bg_feature_name('header')
    runner = Runner(filename, verbosity=1)
    runner.run()
    assert_stdout_lines('..\n1    feature    (1    passed)\n2    scenarios    (2    passed)\n7    steps    (7    passed)\n')

What's a good function header?
