python定时执行代码

Question

我想在每次执行时都在完全相同的时间执行我的一段代码，有点像播放媒体文件...(同一段代码每次都以完全相同的时间执行)

这在 python 中可能吗？

Answer 1

这应该可以解决问题:

def run_with_delay(funcs, interval):
    for f in funcs[:-1]:
        before = time()
        f()
        # compensate the interval with the execution time.
        # NB: careful for functions that have a greater
        #     execution time than interval
        after = time()
        if after - before < interval:
            sleep(interval - (after - before))
    # last function is taken separately because we don't need
    # an extra useless sleep
    funcs[-1]()
