I wrote the below code

    d = defer.Deferred()
    def f(result):
        return result
    d.callback(1)
    d.pause()
    for i in xrange(n):
        d.addCallback(f)
        d.addErrback(f)
        d.addBoth(f)
        d.addCallbacks(f)
    d.unpause()

What's a good function header?

Here's a good function header?
