MNIST is a collection of hand-written digits that is commonly used to play with classification algorithms. It turns out that some compression mechanisms can double as classification tools. This article covers a bit of why with the added code-golf goal of a small amount of code.

In this tutorial, you’ll take a deep dive into parallel processing in Python. You’ll learn about a few traditional and several novel ways of sidestepping the global interpreter lock (GIL) to achieve genuine shared-memory parallelism of your CPU-bound tasks.

不觉中蟒周刊快译已经到了第10+2个年头

开始有小伙伴加入承担 pythonisa 周刊的翻译, 从来没提醒过, 可就这么默默坚持下来了...

问为什么:

[皱眉]每周新闻资讯 怎么能错过 
看看有什么新东西 
当有新的发现时：
    what f**k 还能这样玩？ 还有这东西？
    每周开彩蛋[吃瓜]

无法同意更多... 很多社区贡献看起来辛苦, 其实受益最多的, 就是主动承担者也.
