I wrote the below code

    def run(*args, **kw):
        ts = time.time()
        print (' DCTB testing    function    %r' % method.__name__)
        method(*args, **kw)
        te = time.time()
        print (' DCTB [OK]    in    %r    %2.2f    sec' % (method.__name__, (te - ts)))
    return run

What's a good function header?
