I wrote the below code

    def real_decorator(func):
        @wraps(func)
        def wrapper(self, *args, **kwargs):
            if (setup is not None):
                setup(self)
            for i in range(warmup):
                func(self, *args, **kwargs)
            clock_time_starts = np.zeros((number, repeat))
            clock_time_ends = np.zeros((number, repeat))
            for i in range(number):
                for j in range(repeat):
                    clock_time_starts[(i, j)] = perf_counter()
                    func(self, *args, **kwargs)
                    clock_time_ends[(i, j)] = perf_counter()
            clock_times = (clock_time_ends - clock_time_starts).min(axis=1)
            print '[{}]    with    {}    loops,    best    of    {}:'.format(_get_bench_name(func), number, repeat)
            print ' DCTB min    {:4s}    per    loop'.format(_timeitlike_time_format(clock_times.min()))
            print ' DCTB avg    {:4s}    per    loop'.format(_timeitlike_time_format(clock_times.mean()))
        return wrapper
    return real_decorator

What's a good function header?

=====
Give me a Python program to print '[{}]    with    {}    loops,    best    of    {}:'?
