python设置全局热键

需要使用第三方库, 代码如下:

import tkinter as tk
import keyboard

def output(event):
    #print("From global keystroke")
    print(event)

root = tk.Tk()
root.withdraw()

keyboard.add_hotkey('ctrl+a', output, args=('From global keystroke',))
#keyboard.add_hotkey('ctrl+a', output)
root.mainloop()
