遵循视频指南时，pynput 自定义自动键脚本不起作用

Question

我想创建一个热键，但决定使用 Python 而不是 AHK 来“挑战”自己。

我希望在按下组合键 Ctrl+Alt+P（或 p）时打印出短语 Scheiße!

我参考了this的视频，写了如下脚本：

from pynput import keyboard

COMBINATIONS = [
{keyboard.Key.ctrl, keyboard.Key.alt, keyboard.KeyCode(char='p')}, # Detects ctrl+alt+p
{keyboard.Key.ctrl, keyboard.Key.alt, keyboard.KeyCode(char='P')} # Detects ctrl+alt+P
]

current = set()

def execute():
 print ("Scheiße!") # When the above combo is pressed, the word "Scheiße!" is printed

def on_press(key):
    if any([key in COMBO for COMBO in COMBINATIONS]): # Checks if pressed key is in any combinations
        current.add(key) # If it is, then it's added to the current key set
        if any(all (k in current for k in COMBO) for COMBO in COMBINATIONS): # Checks if every key of the combination has been pressed
                execute() # If all checks pass, execute is called
def on_release(key):
    if any([key in COMBO for COMBO in COMBINATIONS]): # Checks if a key released is in any of the combinations
        current.remove(key) # If it is, then it's remove from the current key set if applicable

with keyboard.Listener(on_press=on_press, on_release=on_release) as listener:
    listener.join()

当我执行脚本时，出现以下错误：

    ================== RESTART: C:\Users\IMSOASIAN\Desktop\Scheiße!.py =================

我尝试了各种故障排除步骤，例如删除德语字符、将“p”和“alt”替换为其他键，但唯一能做的就是更改输出。

有人对此有解决方案吗？

Answer 1

根据你提供的信息，我在VS Code中测试了视频中的代码，可以在VS Code中运行：

请使用代码：

COMBINATIONS = [
    {keyboard.Key.shift, keyboard.KeyCode(char='p')}, # Detects ctrl+alt+p
    {keyboard.Key.shift, keyboard.KeyCode(char='P')} # Detects ctrl+alt+P
]

另外，请重新加载 VS Code 使其能够识别已安装的模块，并尝试在 VS Code 中运行几次。
