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

    def a():
        with xxx() as abc:
            f()
    def f():
        for z in ():
            pass
        (1 / 0)
    class xxx(object, ):
        def __enter__(*args):
            pass
        def __exit__(*args):
            pass
    try:
        a()
    except:
        assert_traceback([((Line496 + 19), 30, 'test_traceback.py', 'test_with_mixed_stack'), ((Line496 + 6), 3, 'test_traceback.py', 'a'), ((Line496 + 12), 3, 'test_traceback.py', 'f')])

What's a good function header?
