Python winsound 按键

Question

I am just learning python and am having difficulty with this piece of code.

def down():
    keyPress = win32api.GetAsyncKeyState(0x06)
    print (keyPress)
    if keyPress < 0:
        winsound.Beep(400,200)
    if keyPress > 0:
        winsound.Beep(200,200)
        winsound.Beep(200,200)

My goal is to have the program play the first (400,200) sound after I press VK_XBUTTON2. Then after pressing VK_XBUTTON2 again, I want it to play the two (200,200) sounds.

In my program the first beep works, and that makes sense as according to the win32api documentation, pressing the button leads to a result of -32767, however how do I check if the button is pressed again? As if keyPress > 0: does not seem to be working.

Answer 1

According to GetAsyncKeyState ,
when the key is down, GetAsyncKeyState will return 0b1000000000000001 and 0b1000000000000000 next time.
when the key is not down but was pressed after the previous call to GetAsyncKeyState , GetAsyncKeyState will return 0b0000000000000001 .
