Python PDF转换工具箱（PDF转图片，word，拆分，删除，提取）
1.简介：
使用Python自写的pdf工具箱，包括pdf转word，图片，合并，页面拆分，页面删除，页面提取、
转换word，图片功能，支持文件拖入。文章末尾已附源码以及打包好的exe文件，大家需要可自行下载学习，喜欢的话给博主点个小小的关注哦，主页还将会更新更多Python相关干货资源，关注不迷路哦！
功能介绍：
合并：添加顺序就是合并顺序，可多次添加。
拆分：将输入页码的范围拆分成每个独立的pdf，单次可输入多个范围。
删除：将输入页码的范围删除，单次可输入多个范围，保存删除后的文件。
提取：将输入页码的范围提取成独立的pdf，单次可输入多个范围。
