开源，一款百度图片下载器，图片合成器。供新手学习使用

井右寺

成品请见https://www.52pojie.cn/thread-1012450-1-1.html
初学的时候写的东西，稍稍整理了一下。发出来供大家参考。（辟邪：大佬勿喷！）
因为感觉会是很好地练手项目，基本上全是基础知识。
另外，因为发布以后，发现很多BUG，但是最近被别的项目缠住了。
所以，开源出来，抓壮丁呀，谁把它完善了哈，毕竟学习还是要实战项目的嘛，这就是个不容错过的机会哦，基本上学习1个月左右就会接触到里面所有的知识点，练手绝佳哈。
todo：
1、下载器的优化，线程使用quene通信，梳理优化，能扩展其它平台最好。
2、合成器，使用聚类优化查询，想法是做一个聚类的链表。
3、图片相似度查询优化，最好能用cv2取代pil（因为自己想学opencv来着）。并且目前存在bug，内存占用过高，大量高质图片会导致溢出错误。
4、GUI优化，打算学qt库。
5、其它语言扩展（想用java来实现一遍，因为java已经被我丢得差不多了，上次我居然连java的数组都不会写了，丢人....）

我也想学学python,该如何开始呢？纯粹业余爱好。
在一个微信公众号里  每天看15分钟，看了有一个星期了。

先看基础语法，浏览完成后，就开始写代码
最开始可能会磕磕绊绊不知道怎么写
遇到不知道怎么办的就查   网上资料挺多
其实语言本身不是特别重要，掌握编程思想才是最重要的
而掌握思想，必须得上手自己撸代码
我最开始只是上菜鸟把基础语法过了一遍，再把阮一峰的教程浏览了几课。就开始动手写爬虫，对着库文档开始撸，遇到不会的马上回去翻文档，一个又一个的写，然后感觉自己有思路了，就回去看别人的代码，看看别人的风格思路，如何优雅的使用一些特性，对照修改自己的。
总而言之，动手写就是了，反正python的实现简单，基本前期的代码写出来，一个功能写完也就几十行不错了。。。。
仅局限于看的话，可能一会儿就忘了，毕竟比较抽象。

闭上的眼镜

万分感谢，终于有大佬解决了。
