sleep时间问题误差太大

Question

import time for i in range(100): t1 = time.time() time.sleep(0.01) print(time.time() - t1) 以上代码是让程序睡眠10ms，我在自己本地运行和网络在线版python运行相比，时间总是网络版本正确，大约是0.0101这种，但本地运行就会变成0.015之类的，明显误差变大，请问有大佬知道这是为啥嘛，感激不尽

Answer 1

import time

while True:
    st = time.time()
    time.sleep(0.001)
    et = time.time()
    print('dt={dt}'.format(dt=et - st))

返回结果：

dt=0.001966238021850586
dt=0.001010894775390625
dt=0.0020058155059814453
dt=0.0010018348693847656
dt=0.001966238021850586
dt=0.0020215511322021484
dt=0.0019714832305908203
dt=0.0010178089141845703
dt=0.0019807815551757812
dt=0.0010159015655517578
dt=0.001965761184692383

这与操作系统有关
