Question

我在Windows 7中通过SSH使用Raspberry Pi，我构建了一个机器人。如果按箭头，它将移动。我用TkInter模块检测到密钥，但它需要一个图形环境。所以如果我只是在SSH终端，它就无法运行。是否有一些模块可以检测到密钥并且不需要窗口？

我没有尝试过，但快速搜索已经显示出来了：

本质上是pyhook的linux实现（仅限windows）

所以要使用它：

import pyxhook
import time

#This function is called every time a key is presssed
def kbevent( event ):
    #print key info
    print event

    #If the ascii value matches spacebar, terminate the while loop
    if event.Ascii == 32:
        global running
        running = False

#Create hookmanager
hookman = pyxhook.HookManager()
#Define our callback to fire when a key is pressed down
hookman.KeyDown = kbevent
#Hook the keyboard
hookman.HookKeyboard()
#Start our listener
hookman.start()

#Create a loop to keep the application running
running = True
while running:
    time.sleep(0.1)

#Close the listener when we are done
hookman.cancel()

没有Tk的Python键被按下
