Guido van Rossum (老爹) 去 Microsoft 了 原文: PyCoder’s Weekly - Issue #447 201118 Zoom.Quiet(大妈) 用时 42 分钟 完成快译 201118 Zoom.Quiet(大妈) 用时 37 分钟 完成格式转抄. PyPy: 不费力就能加速 Python REAL PYTHON In this tutorial, you’ll learn how you can use PyPy to improve the speed of your applications. You’ll see how PyPy compares with other Python implementations like CPython and learn about features that you can use to gain significant performance boosts without making changes to your code. (是也乎: ) 在 .NET 5 上运行 Python ANTHONY SHAW Pyjion is an alternative to the CPython runtime that compiles Python to ECMA CIL and uses .NET common language runtime to compile the CIL to machine code. Learn how Pyjion works, how it compares to other Python runtimes, and what the future holds for the project. (是也乎: 为了欢迎老爹, M$ 也是很拼的… ) 在 PyPI 上猎取恶意软件包 JORDAN WRIGHT Jordan Wright installed every package on PyPI to look for malicious content. And he didn’t just inspect code, he actually ran the packages. Brave soul! Learn how he set-up this project and what he learned on his adventure. 用 Python 模拟量子计算 DANTE SBLENDORIO Learn how to use Python for quantum computing with the QuTiP package, including an introduction to qubits and noise in quantum systems. 用 Cython 包装 C++ 第一部分 ANTON ZHDAN-PUSHKIN • Shared by Anton ZHdan-Pushkin Learn how to wrap a C++ library with Cython in order to expose a Python API. (是也乎: 其实是 C 了… ) Guido van Rossum (老爹) 去 Microsoft 了 TWITTER.COM/GVANROSSUM Retirement was “boring.” (是也乎: 无聊也是最强动机 ) Nikola v8.1.2 已发布 GETNIKOLA.COM CircuitPython 6.0.0-Rc.1 已发布 ADAFRUIT.COM (是也乎: 受到 MicroPython 激发, 而创建的叕一个专注嵌入式系统的 Python 发行版. ) 探讨/吐糟 Discussions ...

Python 正式世界第二 原文: PyCoder’s Weekly - Issue #446 201111 Zoom.Quiet(大妈) 用时 42 分钟 完成快译 201111 Zoom.Quiet(大妈) 用时 37 分钟 完成格式转抄. 在 Python 中作 Key-Driver 分析 BRYCE MACHER Take a look at how statistical knowledge plays an important role in answering business questions like “What drives the winningness of candy?” Along the way you’ll learn how to do Key-Driver analysis in Python on a problem that can’t be easily solved with a call to a machine learning library. 用 Python Defaultdict 类型处理缺少的键 REAL PYTHON course In this step-by-step course, you’ll learn how the Python defaultdict type works and how to use it for handling missing keys when you’re working with dictionaries. You’ll also learn how to use a defaultdict to solve problems like grouping or counting the items in a sequence or collection. (是也乎: Defaultdict 每种新类型, 都需要长久的扫盲. ) 机器学习的距离度量 JAIME ZORNOZA Many machine learning algorithmns can be summarized as transforming data to n-dimensional vectors and computing similarity between points by means of some distance metric. This article explores four of these metrics—the Euclidean, Manhattan, Minkowski, and Hamming distances—and how to compute them with Python. 在 Python 中用 LRU 策略进行缓存 REAL PYTHON Caching is an essential optimization technique. In this tutorial, you’ll learn how to use Python’s @lru_cache decorator to cache the results of your functions using the LRU cache strategy. This is a powerful technique you can use to leverage the power of caching in your implementations. (是也乎: Least Recently Used (LRU) strategy 最小最新可用策略? ) ...
