执行keylogger.py时，在计数计时器中按下每个键时，连续记录动量

Question

下面有下面的代码文件keylogger.py，用于检测按下的特定键并保存到log.txt文件中。我想在这个python代码中添加一个在代码开始运行时启动的计时器，我还希望代码的这一部分能够保存keys从文件开始按下的确切时刻，并将这些信息保存在log.txt文件或另一个单独的文件中(我认为需要使用with open和f.write )。我在How to create a timer on python和https://pythonhow.com/measure-execution-time-python-code/中找到了一些计时思想。

所以我的log.txt会像一样

log.py

RLLR     #this line would already be produced by keylogger.py

R: 0.2s
L:0.24s
L:1.34s
R:2.5s

keylogger.py

from pynput.keyboard import Listener, Key

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



def writeLog(key):
    translate_keys = {
        Key.right: "R",
        Key.left: "L",
    }
    if key in translate_keys:
        with open(logFile, "a") as f:
            f.write(translate_keys[key])

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

使用单独的文件将是最简单的解决方案，我认为：

from pynput.keyboard import Listener, Key
import time

#set log file location for keys pressed
keysLogFile = "/home/diego/keys_log.txt"

#set log file location for keys timestamps
timestampsLogFile = "/home/diego/ts_log.txt"

#store start timestamp
startTime = time.time()


def writeLog(key):
    translate_keys = {
        Key.right: "R",
        Key.left: "L",
    }
    if key in translate_keys:
        currentTime = time.time() - startTime
        with open(keysLogFile, "a") as f:
            f.write(translate_keys[key])
        with open(timestampsLogFile, "a") as f:
            f.write(translate_keys[key] + ": " + str(currentTime) + "s\n")

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

这会给你两个单独的文件：

keys_log.txt

RLLR

ts_log.txt

R: 0.2s
L: 0.24s
L: 1.34s
R: 2.5s
