Python工具开发：PDF转Word、Word转PDF、PDF转图片、Excel查询

最近生活中经常需要对Word和PDF两个文件类型进行互转，挺麻烦的，这个时候就有两个选择，要么百度搜索那些在线转换类型的网站，要么只能使用微软office全家桶自带的类型转换，前者因为文件涉及我的个人隐私，所以我不是很想在那些网站上进行转换，虽然说没人在意我那些资料，哈哈！安全点还是好的，那么我就只能选择微软自带的功能了，我之前用过一次感觉还不错很好用，可是当我第三次使用的时候发现，居，居然，要钱了

"""
当然在学习Python的道路上肯定会困难，没有好的学习资料，怎么去学习呢？

我还以为微软那个是每天两次机会，没想到居然是一个账号两次机会啊，打扰了，饭都吃不起，那还有钱啊，而且居然这么贵

所以推出了Excel2.0版本，别问为什么，懒得重新绘制界面，拿上个帖子的模板的修修改改，又是个新的，就是那个被吐槽难看的那个模板，我换了个皮又拿出来了，没想到吧！！
好了，不说废话了，新的软件操作简单，先导入文件然后单击按钮就可以了（其实刚设定的时候连按钮都没，直接导入就自动转换了，后面想想，可能有些人不喜欢这种模式，所以改回了传统鼠标单击按钮），现在是可拖放也可导入，随便了，其他我做了限制，不是规定文件不能转换，比如Word转PDF，你导入PDF然后点击Word转PDF就不行，没办法不设置，到时候又软件有bug，转换完，会在左下角提示转换成功和文件路径的
有一个前提要求电脑要有Word，Excel，PDF，不然软件用不了，会闪退

吸取评论区的建议，新加了PDF转Word，因为win7的分辨率，同时缩小了软件界面，软件在上面的阿里云里，根据需求自行下载正常版和迷你版
迷你版成品图

正常大小的成品图

测试的时候出现闪退现象，大概率是因为电脑没有office全家桶，就是Excel，word，pdf这些软件，小概率是因为你电脑已经有同个类型同个名称的文件了
如果文件较大，卡顿是正常情况，不用理会的，它只是这个软件未响应，不影响电脑正常使用，该打游戏的打游戏，办公的办公，等它处理完就恢复了！！！！！
还有这个排版真的难受，自动给你文字中间加一条线，是啥意思.............
