Python使用everything库构建文件搜索和管理工具
作者：winfredzhang
在这篇博客中,我将分享如何使用 Python 的 everytools库构建一个简单的文件搜索和管理工具,这个工具允许用户搜索文件、查看文件路径、导出文件信息到 Excel,以及生成配置文件,文中有相关的代码示例供大家参考,需要的朋友可以参考下
项目概述
这个工具的主要功能包括：
- 文件搜索：用户可以输入关键字来搜索文件。
- 文件管理：用户可以查看搜索结果，选择文件并将其添加到管理列表。
- 数据导出：用户可以将管理列表中的文件信息导出为 Excel 文件。
- 配置文件生成：用户可以生成配置文件，方便后续使用。
环境准备
确保安装了以下库：
pip install wxPython pandas pywin32,everytools

代码解析
界面布局
代码使用 wx.BoxSizer 来布局界面组件，包括搜索框、两个列表视图和多个按钮。每个组件都有相应的事件绑定，用于处理用户交互。
文件搜索功能
用户在搜索框中输入关键字，按下回车后，程序会调用 EveryTools 类进行搜索，并将结果显示在第一个列表视图中。如果没有找到结果，程序会弹出提示框。
文件管理功能
用户可以通过双击搜索结果，将文件添加到第二个列表视图中。选中的文件可以被删除。
数据导出与配置文件生成
用户可以将第二个列表视图中的文件信息导出为 Excel 文件，或生成配置文件。
结果如下
总结
这个简单的文件搜索和管理工具展示了 everytools的基本用法，适合初学者学习和实践。通过这个项目，您可以了解如何处理用户输入、管理列表视图和文件操作等。
