• Python在IEEE“顶级编程语言”中排名第一
  • IEEE.ORG

“Python dominates as the de facto platform for new technologies” and “Learn Python. That’s the biggest takeaway we can give you from its continued dominance of IEEE Spectrum’s annual interactive rankings of the top programming languages. You don’t have to become a dyed-in-the-wool Pythonista, but learning the language well enough to use one of the vast number of libraries written for it is probably worth your time.”

• skybison: Instagram 的实验性能面向 Feenfield Python 实现
  • GITHUB.COM/FACEBOOKEXPERIMENTAL

“Skybison is experimental performance-oriented greenfield implementation of Python 3.8. It contains a number of performance optimizations, including: small objects; a moving GC; hidden classes; bytecode inline caching; type-specialized bytecode; an experimental template JIT.”

• 如何在定义 Python 函数时使用可选参数
  • REAL PYTHON

In this tutorial, you’ll learn about optional arguments in Python and how to define functions with default values. You’ll also learn how to create functions that accept any number of arguments using args and kwargs.

Discussions

• math.sqrt vs numpy.sqrt vs x ** 0.5 性能讨论
  • TWITTER.COM/KARPATHY

Andrej Karpathy (Director of AI at Tesla) shares an interesting performance observation on this Twitter thread that turns into a tale about accurate benchmarking. Calculating math.sqrt(1337.0) appears to be 10x faster than numpy.sqrt(1337.0). Python’s built-in square root (x ** 0.5) appears to be even faster. However, most of the performance differences seem to come from the benchmark setup, as Ishan Bhatt explains in this writeup.

• 150 行 Python 完成一个 SQL 查询生成器
  • ANDGRAVITY.COM

“This is the fourth article in a series about writing my own SQL query builder. Today, we’ll rewrite it from scratch, explore API design, learn when to be lazy, and look at worse and better ways of doing things – all in 150 lines of Python!”

• 用 scikit-searn 和 train_test_split() 拆分数据集
  • REAL PYTHON
  • video

Learn why it’s important to split your dataset in supervised machine learning and how to do that with train_test_split() from the widely used scikit-learn package.

不觉中蟒周刊快译已经到了第9个年头

去年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.
