使用pynput.Listener和keylogger监听特定的键吗？

Question

我下面有以下python脚本：

但是我想“听”，或者如果足够的话，只需将以下键“记录”到我的log.txt中：Key.left和Key.up。我如何造成此限制？

[此question相似，但其响应的代码结构有所不同，需要进行重大更改以允许键盘记录程序和对此Listener的限制。

[另外question在我看来似乎是寻找解决方法的灵感之源。

我花了一些时间寻找可以给我这个答案或帮助我思考的问题，但我找不到它，但是如果已经发布了一个问题，请告诉我！

How to create a Python keylogger：

#in pynput, import keyboard Listener method
from pynput.keyboard import Listener

#set log file location
logFile = "/home/diego/log.txt"

def writeLog(key):
    '''
    This function will be responsible for receiving the key pressed.
     via Listener and write to log file
    '''

    #convert the keystroke to string
    keydata = str(key)

    #open log file in append mode
    with open(logFile, "a") as f:
        f.write(keydata)

#open the Keyboard Listener and listen for the on_press event
#when the on_press event occurs call the writeLog function

with Listener(on_press=writeLog) as l:
    l.join()

您可以从Key导入pynput.keyboard模块并检查击键的类型。

#in pynput, import keyboard Listener method
from pynput.keyboard import Listener, Key

#set log file location
logFile = "/home/raj/log.txt"

def writeLog(key):
    '''
    This function will be responsible for receiving the key pressed.
     via Listener and write to log file
    '''

    if(key == Key.left or key == Key.up):
        #convert the keystroke to string
        keydata = str(key)

        #open log file in append mode
        with open(logFile, "a") as f:
            f.write(keydata)

#open the Keyboard Listener and listen for the on_press event
#when the on_press event occurs call the writeLog function

with Listener(on_press=writeLog) as l:
    l.join()
