我在本地撰写文件.如何像远程主机上运行的集装箱捆docker-compose up -d带DOCKER_HOST=<some ip>？

我想测量在Python 3中进行加法运算所需的时钟周期数.

我写了一个程序来计算加法运算的平均值:

from timeit import timeit

def test(n):
    for i in range(n):
      1 + 1

if __name__ == '__main__':

    times = {}
    for i in [2 ** n for n in range(10)]:
      t = timeit.timeit("test(%d)" % i, setup="from __main__ import test", number=100000)
      times[i] = t
      print("%d additions takes %f" % (i, t))

    keys = sorted(list(times.keys()))

    for i in range(len(keys) - 2):
      print("1 addition takes %f" % ((times[keys[i+1]] - times[keys[i]]) / (keys[i+1] - keys[i])))

输出:

16 additions takes 0.288647
32 …
