按键检测

Question

我一直在尝试在Python程序中检测到按键.我想找到一种方法来做到这一点,而不使用Tkinter curses,或raw_input.这是我要做的:

while True:
    if keypressed==1:
        print thekey

有谁知道这有可能吗？

Answer 1

Python有一个具有许多功能的键盘模块.安装它,也许使用此命令:

pip3 install keyboard

然后在代码中使用它:

import keyboard #Using module keyboard
while True:#making a loop
    try: #used try so that if user pressed other than the given key error will not be shown
        if keyboard.is_pressed('a'): #if key 'a' is pressed 
            print('You Pressed A Key!')
            break #finishing the loop
        else:
            pass
    except:
        break #if user pressed other than the given key the loop will break

您可以设置多个密​​钥检测:

if keyboard.is_pressed('a') or keyboard.is_pressed('b') or keyboard.is_pressed('c'):
    #then do this
