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

    import nose
    if (t is None):
        return (lambda x: _network(x, url=url))
    def wrapper(*args, **kwargs):
        try:
            f = urlopen(url)
        except (IOError, HTTPException):
            raise nose.SkipTest()
        else:
            f.close()
            return t(*args, **kwargs)
    return wrapper

What's a good function header?
