(是也乎: 面试已经成为一门显学, 无论面试时考查的东西和实际工作中有无关系, 面试难度, 已经成为一家企业的 face 了. ) 用 NumPy 进行数组编程 CHARLES R. HARRIS ET AL In this review published in Nature and co-authored by NumPy creator Travis Oliphant, the authors explore how NumPy increasingly acts as an interoperability layer between array computation libraries like PyTorch and Tensorflow. (是也乎: 除非象 PyTorch 要用细致的矩阵控制, 否则, 还是通过 Pandas 来用 NumPy 来的自然. ) 例外当控制流程 GEORGE opinion Using exceptions as control flow is a practice typically discouraged, and for some good reasons.

(是也乎: 嗯哼, 允许自我推荐的? 不过, 这个漫画风格是喜欢的. ) Python 中的面向数据的编程 BRIAN KIHOON LEE Python’s success in scientific and numerical computing is based largely on the performance of libraries like NumPy and SciPy. What is is that makes NumPy so effective, and where is numerical Python is headed in the future? (是也乎: 面向数据编程, 嗯哼, 18年前, Limodou 在 PyCon中国大会上就提出过, 其实, 所有编程语言, 本质上都是这个实践行为; 只是有的语言将这个思想融合到了自身,比如说 LISP; 有的只能通过各种模块来融合. ) 用 conda-pack 收缩您的 Conda Docker 映像 ITAMAR TURNER-TRAURING If you’re building a Docker image that’s based on Conda, the resulting images can be huge. Learn one way to do shrink image sizes, by combining the conda-pack tool with multi-stage builds. (是也乎: 甩干技巧. ) The Real Python Podcast – Episode #26: 与Michael Kennedy 一起 Python 播客的5年: 成长/GIL/异步等 REAL PYTHON podcast Why is Python pulling in so many new programmers? Maybe some of that growth is from Python being a full-spectrum language. This week on the show we have Michael Kennedy, the host of the podcast “Talk Python to Me”. Michael reflects on five years of podcasting about Python, and many of the changes he has seen in the Python landscape. (是也乎: ) pip 可用性调查 PYTHON SOFTWARE FOUNDATION (是也乎: 这个问卷大家都应该积极嗯哼一下, 光是加速墙内 pip 镜像群, 就值得嗯哼了.. ) Python 101 第二版发布 MIKE DRISCOLL seaborn 0.11.0 现已发布 PYDATA.ORG (是也乎: seaborn 好同志, 是 matplotlib 的专用形象设计师, 真爱. ) 所有低于3.6的Python版本现已 EOL PYTHON.ORG (是也乎: End of Life (EOL) release cycle is frozen; no further changes can be pushed to it. 嗯哼? 俺比较好奇的是 Łukasz 怎么念? ) 探讨/吐糟 Discussions ...

(是也乎: 一门语言是否有统治地位, 还得看是否经得住上天, 毕竟在外空间, 硬盘都随时有字节被反转的可能, 所以, 对应运行时的容错能力就非常重要了… ) 一个 Bash 命令开始新的一天 DOAA MAHELY When faced with the repetitive task of opening the same browser tabs, the same code IDE, and starting the same local server to start her workday, one resourceful Pythonista wrote a Python script to simplify her morning routine. (是也乎: 将 Py 脚本注入 Bash … 更多乐趣, 更难迁移… ) 适用于 Python 的“结构模式匹配”/第2部分 JAKE EDGE The saga of PEP 622 continues with updates to the proposed structure of the match statement—which has some similarities to a switch statement—and a discussion on the best way to document objections to a PEP.
