我发现使用 pyHook 可以打印鼠标上下点击的脚本：

class record(object):
    def OnMouseEvent(self, event):
        print 'MessageName:',event.MessageName
        print 'Message:',event.Message
        print 'Time:',event.Time
        print 'Window:',event.Window
        print 'WindowName:',event.WindowName
        print 'Position:',event.Position
        print 'Wheel:',event.Wheel
        print 'Injected:',event.Injected
        print '---'
        #time.sleep(1) #If I uncomment this, running the program will freeze stuff, as mentioned earlier.
        return True

Record = record()
hm = pyHook.HookManager()
hm.MouseAll = Record.OnMouseEvent
hm.HookMouse()
pythoncom.PumpMessages()

当我使用 pyHook 以相同的方式检测键盘上的上下键时，它只显示了按键

def OnKeyboardEvent(event): 
    print ('MessageName:',event.MessageName )
    print ('Message:',event.Message)
    print ('Time:',event.Time)
    print ('Window:',event.Window)
    print ('WindowName:',event.WindowName)
    print ('Ascii:', event.Ascii, chr(event.Ascii) )
    print ('Key:', event.Key)
    print ('KeyID:', event.KeyID)
    print ('ScanCode:', event.ScanCode)
    print ('Extended:', event.Extended)
    print ('Injected:', event.Injected)
    print ('Alt', event.Alt)
    print ('Transition', event.Transition)
    print ('---')    
    return True
# When the user presses a key down anywhere on their system 
# the hook manager will call OnKeyboardEvent function.     
hm = pyHook.HookManager()
hm.KeyDown = OnKeyboardEvent
hm.HookKeyboard()
try:
    pythoncom.PumpMessages()
except KeyboardInterrupt:
    pass

我怎样才能检测到按键？

这真的很晚了，但希望它可以帮助某人。您只是将钩子管理器注册到按键事件，所以这些是唯一显示的。您还需要订阅 KeyUp 事件。您可以将它们注册到相同的函数，如图所示，但请注意，可能对于一个项目，您可能希望为它们订阅不同的方法。

def OnKeyboardEvent(event): 
    print ('MessageName:',event.MessageName )
    print ('Message:',event.Message)
    print ('Time:',event.Time)
    print ('Window:',event.Window)
    print ('WindowName:',event.WindowName)
    print ('Ascii:', event.Ascii, chr(event.Ascii) )
    print ('Key:', event.Key)
    print ('KeyID:', event.KeyID)
    print ('ScanCode:', event.ScanCode)
    print ('Extended:', event.Extended)
    print ('Injected:', event.Injected)
    print ('Alt', event.Alt)
    print ('Transition', event.Transition)
    print ('---')    
    return True

# When the user presses a key down anywhere on their system 
# the hook manager will call OnKeyboardEvent function.     
hm = pyHook.HookManager()
hm.KeyDown = OnKeyboardEvent
# Here we register the same function to the KeyUp event. 
# Probably in practice you will create a different function to handle KeyUp functionality
hm.KeyUp = OnKeyboardEvent
hm.HookKeyboard()
try:
    pythoncom.PumpMessages()
except KeyboardInterrupt:
    pass

此外，根据您的 Python 版本，如果您在 OnKeyboardEvent 结束时未返回 True，则可能会遇到错误。您可能还想花一些时间阅读 HookManager.py。快乐的键盘记录！呃呃，孩子们注意安全
