Python + Tkinter + pyttsx3实现的桌面版英语学习工具

在多行文本框输入英文句子，双击其中的英文单词，给出英文读音和中文含义和音标。

本程序查询本地词典数据。通过菜单栏"文件"->"打开词典编辑器"进入编辑界面。

词典数据存储在独立的dictionary.json文件中，这个文件需要和程序文件在同一文件夹中，否则将自动建立一个。

编辑器实现了完整的CRUD（创建、读取、更新、删除）功能

添加单词：直接填写所有字段后点击"添加单词"

编辑单词：从列表选择单词 -> 修改字段 -> 点击"保存修改"

删除单词：从列表选择单词 -> 点击"删除选中"

pyttsx3 是一个文本到语音（Text-to-Speech, TTS）转换库，它允许你在 Python 程序中将文本转换为语音输出。它是第三方库需要安装使用。

在cmd中，使用 Python 包安装命令安装：pip install pyttsx3

若安装了多个python版本，X.Y代表Python版本，多余的部分舍弃如3.8.1取3.8，3.10.5取3.10，即只取第二个点前的部分。仅安装了一个python版本不需要。pip命令默认会连接在国外的python官方服务器下载，速度可能比较慢，使用镜像网址可以加快速度：-i 镜像网址

py -3.12 -m pip install 第三方库名 -i https://pypi.tuna.tsinghua.edu.cn/simple

py -3.12 -m pip install pyttsx3 -i https://pypi.tuna.tsinghua.edu.cn/simple
