如何使用库键盘在python中同时注册多个按键

发布于07月25日

我想创建一个程序，当我按下ctrl键和alt键的同时，刷新页面100次.唯一不起作用的是同时按ctrl和alt.有人知道如何解决这个问题吗.这是我的密码

import pyautogui
import keyboard

while True:  
    try:  e
        if keyboard.is_pressed('ctrl,alt'):  
            print('You Pressed h Key!')
            pyautogui.hotkey('f5') 

    except:
        break

推荐答案

如果显示错误-即.

except Exception as ex:
    print('Exception:', ex)

然后你会看到(至少在Linux上)

Exception: Impossible to check if multi-step hotkeys are pressed (`a+b` is ok, `a, b` isn't).

这表明你需要ctrl+alt而不是ctrl,alt

import keyboard

while True:
    try:
        if keyboard.is_pressed('ctrl+alt'):
            print('You Pressed ctrl+alt')
    except Exception as ex:
        print('Exception:', ex)
        break

EDIT:

也适合我

if keyboard.is_pressed('ctrl') and keyboard.is_pressed('alt'):

和add_hotkey()

import keyboard

def update():
    print('You Pressed ctrl+alt')

keyboard.add_hotkey('ctrl+alt', update)

keyboard.wait('esc')  # press `Esc` to end program
