python应用win32api模拟鼠标点击操作，正常调用没有问题，等息屏后调用就报错，求教

[Micross]

def dianji_shubiao():
    win32api.SetCursorPos([68,84])
    # 鼠标点击
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN,0,0) 
    time.sleep(1)
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP,0,0)
    time.sleep(1)
    print("dianji_shubiao")

time.sleep(delta_time)
dianji_shubiao()

代码如上，正常调用时，没有问题，点击模拟操作可以生效，如果sleep是一个很长时间，等人走了电脑息屏，就会报错不成功。报错如下：
File "D:\test.py", line 40, in dianji_shubiao
win32api.SetCursorPos([68,84])
pywintypes.error: (0, 'SetCursorPos', 'No error message is available')

    time.sleep(1)

    print("dianji_shubiao")
 
time.sleep(delta_time)

这样能用吗

import ctypes
ctypes.windll.user32.SetCursorPos(68,84)
