• 比较Rust,Haskell,C,Python,Scala和OCaml中的相同项目
  • TRISTAN HUME

"A rare opportunity to compare implementations of large programs that all did the same thing, written by friends I knew were highly competent, and have a fairly pure opportunity to see what difference design and language choices could make."

• 走向 "Kernel Python"
  • GLYPH LEFKOWITZ
  • opinion

"We need a newer, leaner, unburdened 'kernel' Python. We need to dump the whole standard library out on the floor, adding back only the smallest bits that we need, so that we can tell what is truly necessary and what's just nice to have."

• 在 Python 中用 main.py
  • SHANE O'NEILL

"The magic file main.py is called when you run your project with the -m module flag. If you code is intended to be used a module first, and command line interface second, this makes perfect sense to use. Think of it as a place we can put whatever would be in our body of our if name === "main" statement."

• PyPI现在支持通过 WebAuthn 进行双因登录
  • PYFOUND.BLOGSPOT.COM

"To further increase the security of Python package downloads, we're adding a new beta feature to the Python Package Index: WebAuthn support for U2F compatible hardware security keys as a two-factor authentication (2FA) login security method."

• PSF公布2019年董事会选举结果
  • TWITTER.COM/THEPSF

• 想为 CPython 做贡献, 姿势都在这里
  • JOANNAH NANJEKYE

"I will try to explain how you can start contributing to CPython borrowing from some few ways I have used and found to work for me."

(是也乎:

详解, 如何为 CPython 贡献

)

• 循环更好:深入研究Python中的迭代
  • TREY HUNNER

"Python's for loops don't work the way for loops do in other languages. In this article we're going to dive into Python's for loops to take a look at how they work under the hood and why they work the way they do."

• 用 ActiveState 几分钟内构建 Python
  • ACTIVESTATE
  • sponsor

Tired of Conda-installing? Automatically build your Python runtime environment with the packages you need: Automatically resolve dependencies, install in a virtual environment with a single command, build Python 2.7 and 3.6 on Linux and Windows. Learn more →

(是也乎:

ACTIVESTATE 居然还活着?

• 如何用 Argparse 在 Python 中构建 CLI
  • REAL PYTHON

In this step-by-step Python tutorial, you'll learn how to take your command line Python scripts to the next level by adding a convenient command line interface that you can write with argparse.

(是也乎:

Argparse 不错...只是... Click 们更加现代.

• Python vs R — 为数据科学选择最佳编程语言
  • JUN WU opinion

"Functional Programming vs. Imperative Programming, the Nature of R Programming versus Python Programming, Data Science Tasks all determine what programming language to use in Data Science Project."

(是也乎:

反正, 数据清洗什么的 Py 最顺手... )

• 在 Go 和 Python 或 R 之间进行通信
  • MATTHEW MAHOWALD

"Sometimes, we need code from one language to call code written in another language directly. In this post, we'll take a short look at how to do that using C foreign function interfaces (FFI) as a way to call functions written in Go using Python."

(是也乎:

C 永远丢不了

)

• 用 Docker 更快构建 Pipenv,Poetry 或 Pip-Tools
  • ITAMAR TURNER-TRAURING

"Installing dependencies separately from your code allows you to take advantage of Docker's layer caching. Here's how to do it with pipenv, poetry, or pip-tools."

(是也乎:

测试过, 上 Docker 比 Pipenv 祼跑至少多4倍空间, 每次 )
