写完想着记录点什么，就写下了这篇自己看的博客，记录一下心路历程。
运行效果图
功能实现
1）多页PDF文档给页面标序号
2）单页PDF可以复制多份。第一个复制的页面标1，第二个复制的页面标2，以此类推
实现思路
之前完成过一个图片标序号的小脚本，PDF标序号的话，可以先转成图片，然后图片标序号，最后把图片整合起来，功能实现以后想着做个界面的东西，好看点，最后把代码打包成exe，直接就能使用了，ok想完说干就干
环境准备
python 3.6 64位（安装PythonMagick需要下载对应版本，不然报错） 用到的库：tkinter，PyPDF2，PythonMagick，reportlab
实现过程
开始整python没多久，没做到任何库随手拿来用的地步，所以就是漫长的百度过程，看别人的教程、博客，仿写改写，然后看API用法熟悉一下
用到的库：tkinter，PyPDF2，PIL
PDF标序号主要参考博客：1） #主要功能实现参考这个就行
2） #图片转PDF
tkinter部分主要参考教程：1）https://morvanzhou.github.io/tutorials/python-basic/tkinter/ #tkinter基础
2） #事件绑定
exe打包参考教程：

遇到的问题
1）运行出现RunTimeError，自己PC上可以运行，依赖库装完后笔记本上运行出现的错误，思前想后就ghostscript没有安装。安装以后完美运行
2）进程已结束,退出代码-1073741819 (0xC0000005) 。这时候功能实现了，我想转换600多页的一个PDF文档时报的错，百度没有找到好的解决办法，猜测可能是占内存太大异常退出了（目前已解决，但是效率有点慢，待优化ing）
3）
，遇到这个百度很久也没解决，超出目前能力范围，希望有人以后能告诉我答案，这导致的问题是复制的PDF像素都不高4 )
https://github.com/mstamy2/PyPDF2/issues/438 ---可以参考这个
应该还遇到其他各种各样问题的，想不起来了，如有人看到这可以评论留言遇到的问题，我看看我有没有遇到
立个flag：下次一定边记录问题边写博客！！！
