python技巧系列源码

地址

python技巧🐍系列视频的所有代码,个别章节可能包含图片,ppt,导图文件。

说明

项目中可能会含有计划录但还没有录的代码内容,这部分内容可能涉及剧透。不太建议看,因为如果你已经看了,再看b站视频可能就没啥意思了 /* 尤其是迷惑行为 */,但如果你不经常看b站,经常看github,那就都可以了。

分类

三位数的序号是up的视频中对应的标题序号,表示up的更新时间顺序,使用map.py更新map.md时要用到(对应文件夹和b站视频)

🐍python迷惑行为

一些没有用的奇怪写法和“寄巧”可能会被收录到迷惑行为中,偏向娱乐和整活。里面开的“同事、老师、同学、舍友”的玩笑请不要当真。同时,里面的一些危险代码操作也不要轻易模仿。

做视频的初衷

最早

这个视频最早是打算发纯算法视频讲解的,我的视频质量很低,录制效果也不好。其实我知道不会有多少人看的,但是我依然发了,目的是想给自己做一个记忆保存的功能,我一旦忘了某一个算法,我稍微一看自己以前讲过的视频,就能够立刻回忆起来了,并且我发现自己对着电脑讲出来,再剪辑一遍,再加上讲之前的准备,真的会印象深刻,记忆很久。

有一天我翻开我曾经总结的所有二级公式和结论骚操作的高中笔记、遗憾的是我很多东西我都忘了,有些结论和公式我已经忘记是怎么来的了。所以我想到了记忆保存

希望未来会更好。

算法向

python有很多内置的功能和库,在写算法题的时候能很方便的写好,而其他语言来说就会相对麻烦,尤其是面对leetcode周赛这种拼手速的场合,用python秒杀第一道简单题那是最合适不过了。(有些场合的算法比赛拿一血甚至有特殊奖励)所以up决定总结一下python的所有对算法有利的库和方法。这些方法融汇、散布在这个系列里。

注:过于依赖骚操作、语言特性、调库、不利于算法起步阶段,初学算法应注重基础。

写在最后

若有建议可面留个言
