我正在尝试编写在双击 CTRL 后执行某些操作的脚本。第一次双击后效果很好，但后来我得到了那个错误。此外，如果我在计时器执行功能触发后一次又一次地按 CTRL，我会得到同样的错误。

import pythoncom, pyHook, threading

press = False

def triger():
    global press
    press=False
    
def something():
    print 'hello'
    
def OnKeyboardEvent(event):
    global press
    if event.Key=='Lcontrol':
        if press:
            something()
            press = False
        else:
            press=True
            threading.Timer(1,triger).start()
            

hm = pyHook.HookManager()
hm.KeyDown = OnKeyboardEvent
hm.HookKeyboard()
pythoncom.PumpMessages()

错误：

hello

根据文档，在 OnKeyboardEvent 函数的末尾必须有“return True”。这是它的样子。

def OnKeyboardEvent(event):
    global press
    if event.Key=='Lcontrol':
        if press:
            something()
            press = False
        else:
            press=True
            threading.Timer(1,triger).start()
            print 'waiting'
    return True
