python代码实现键盘按键控制循环的暂停和结束

a控制暂停，b控制结束

import keyboard
import time

paused = False
stop = False


def on_press(event):
    global paused
    global stop

    if event.name == 'a':
        paused = not paused

    if event.name == 'b':
        stop = not stop


keyboard.on_press(on_press)

for i in range(1000):
    print(i)
    time.sleep(1)
    if stop:
        break
    else:
        stop_flag = 0

    while True:
        if stop:
            stop_flag = 1
            break

        if paused:
            continue
        else:
            break

    if stop_flag:
        break
