python3中是否有任何命令/模块可以帮助运行一个函数x秒,然后移到程序的另一部分?

# Python Program - Shutdown Computer import os import time check = int(input("enter the seconds")) for i in range ( 10,0): print(i) # time.sleep(1) while i<check : c=input("enter any key to stop") if c exit(); os.system("shutdown /s /t 1")

也许考虑一个线程方法。

此解决方案适用于Windows。

对于Win和Linux,请尝试键盘模块: https://pypi.org/project/keyboard/

import os
import threading
import time
import msvcrt
import queue
import sys

WAIT = 5  # seconds


def keypress(out_q):
    t = threading.currentThread()
    while getattr(t, "do_run", True):
        x = msvcrt.kbhit()
        if x:
            ret = ord(msvcrt.getch())
            out_q.put(ret)


q = queue.Queue()
key = threading.Thread(name="wait for keypress", target=keypress, args=(q,))
key.start()
print("waiting", WAIT, "seconds before shutdown - to abort hit <SPACE>.")
start_time = time.time()
now = time.time()
data = ""
counter = 0
sys.stdout.write(str(WAIT) + "... ")
while now - start_time < WAIT and not data == 32:  # 32 = space bar
    now = time.time()
    try:
        data = q.get(False)
    except queue.Empty:
        pass
    if now - start_time > counter + 1:
        counter += 1
        sys.stdout.write(str(WAIT - counter) + "... ")

    sys.stdout.flush()

key.do_run = False
key.join()

if data == 32:
    print("\n\nok. exiting...")
    exit()

print("\n\nUser did NOT abort - code continues here...")
# Do whatever
