如何同时运行 2 个 While 循环

Question

当我运行它，我只看到打印的“用户移动”而不是时钟，我需要他们同时工作，因为他们有不同的等待时间。 第一个 function 每秒等待，第二个 function 等待 3.5 秒。

import time
import multiprocessing


def get_timer(t):
    mins = t // 60
    hours = 0
    if mins > 59:
        hours = int((mins / 60))
        mins = int(mins % 60)
    secs = int(t % 60)
    clock = '{:02d}:{:02d}:{:02d}'.format(hours, mins, secs)
    return clock


def set_clock(start_time, t):
    while (time.time() - start_time) < t:
        print("----")
        clock = get_timer(int(round(t - (time.time() - start_time), 0)))
        print(clock)
        print("----")
        time.sleep(0.99)
    else:
        print(f'Finished')
        return


def move_user(start_time, t):
    while (time.time() - start_time) < t:
        print('User Moved')
        time.sleep(0.35)
    else:
        print(f'Finished')
        return


times = int(input("Enter The Number Of Times: "))
start = time.time()
p1 = multiprocessing.Process(target=move_user, args=(start, times))
p2 = multiprocessing.Process(target=set_clock, args=(start, times))

if __name__ == '__main__':
    p2.start()
    p1.start()
    p2.join()
    p1.join()

您可以使用asyncio.gather同时运行两个 while 循环

import asyncio
async def set_clock(start_time, t):
   #other stuff
   print('---')
   await asyncio.sleep(0.99)

async def move_user(start_time, t):
    while (time.time() - start_time) < t:
        print('User Moved')
        await asyncio.sleep(0.35)
    else:
        print(f'Finished')
        return

if __name__ == '__main__':
   asyncio.run(asyncio.gather(move_user(start_time, t), set_clock(start_time, t))
# or in a async function

await asyncio.gather(move_user(start_time, t), set_clock(start_time, t)
