多线程应该关闭整个过程，但不能

问题描述

我试图做一个导入PDF的简单可执行文件，并用pyttsx3读取PDF。 由于pyttsx3无法暂停阅读，因此我使用psutil创建了一个小函数，该函数杀死了名为Python.exe的进程（可能不是理想的方法）。 Easygui的简单界面允许选择PDF文件，从哪里开始的页面，以及在按下按钮时（使用psutil）关闭该过程。

据我所知，多线程应该有一个执行多线程的主进程。因此，我认为关闭整个过程会在用户按下按钮时停止脚本。没用 该线程已关闭，但主进程未关闭，因此脚本保持运行状态（语音保持读取状态）。 有可用的版本后，我计划使用pyinstaller将其转换为exe文件。

代码是：

from pyttsx3 import *
from pyttsx3.drivers import sapi5
from PyPDF2 import PdfFileReader
from threading import *
from psutil import process_iter
from easygui import enterBox,fileopenBox,msgBox,choiceBox

class Audiobook():

    def readbook(self,title,page=0):
        book = open(title,'rb')
        pdfReader = PdfFileReader(book)
        pages = pdfReader.numPages
        speaker = init()

        speaker.setProperty('rate',150)
        
        for num in range(page-1,pages):
            page = pdfReader.getPage(num)
            text = page.extractText()
            speaker.say(text)
            speaker.runAndWait()
            speaker.say("You arrived to page" + str(num+1))

    def title(self):
        title = fileopenBox()
        if title:
            page = int(enterBox("From which page would you like to read? ",'Choose the page'))
        else:
            return
        self.readbook(title,page)

    def killprocess(self):
        kill = msgBox("Click here to stop reading","Close the Application?")
        if kill is not None:
            procname = 'Python.exe' #this line will be changed when converted into an executable with pyinstaller
            for proc in process_iter():
                if proc.name() == procname: 
                    proc.kill()

processcontrol = Audiobook()
bookreader = Audiobook()
process1 = Thread(target=bookreader.title)
process2 = Thread(target=processcontrol.killprocess)
process2.start()
process1.start()

知道我在做什么错吗？我欺骗了Google和该网站，但没有成功。

谢谢

解决方法

我更改了终止过程，仅创建了一个对象（不需要两个实例）。

import pyttsx3
from pyttsx3.drivers import sapi5
from PyPDF2 import PdfFileReader
from threading import Thread
from psutil import process_iter
from easygui import enterbox,fileopenbox,msgbox,choicebox
import os
import signal

class Audiobook():

    def readbook(self,title,page=0):
        book = open(title,'rb')
        pdfReader = PdfFileReader(book)
        pages = pdfReader.numPages
        speaker = pyttsx3.init()

        speaker.setProperty('rate',150)

        for num in range(page-1,pages):
            page = pdfReader.getPage(num)
            text = page.extractText()
            speaker.say(text)
            speaker.runAndWait()
            speaker.say("You arrived to page" + str(num+1))

    def title(self):
        title = fileopenbox(default="*.pdf",filetypes=["*.pdf"])
        if title:
            page = enterbox("From which page would you like to read? ",'Choose the page')
            page = 1 if page=="" else int(page)
        else:
            return
        self.readbook(title,page)

    def killprocess(self):
        kill = msgbox("Click here to stop reading","Close the Application?")
        if kill is not None:
            os.kill(os.getpid(),signal.SIGTERM)

bookreader = Audiobook()
process1 = Thread(target=bookreader.title)
process2 = Thread(target=bookreader.killprocess)
process2.start()
process1.start()
