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

    import signal
    try:
        sigNumber = getattr(signal, sigName)
    except AttributeError:
        return
    def handler(sig, f):
        sys.exit(message)
    try:
        signal.signal(sigNumber, handler)
    except ValueError:
        pass

What's a good function header?
