原文: Import Python Weekly Newsletter - Issue No 106 欢迎, 来 PyChina/weekly 共同翻译/增订/推荐 周刊 蠎消息 ;-) 该读 ~ 文章, Blog, 教程… Go 跑 Python! golang, grumpy Grumpy is an experimental Python runtime for Go. It translates Python code into Go programs, and those transpiled programs run seamlessly within the Go runtime. We needed to support a large existing Python codebase, so it was important to have a high degree of compatibility with CPython (quirks and all). The goal is for Grumpy to be a drop-in replacement runtime for any pure-Python project. Curator’s note - If you are a Go Programming Language Developer do checkout http://importgolang.com/newsletter/ (是也乎: 玩具级,看爹了… ) 亲,2017 愿意升级到 Python 3.x 嘛? importpython Take the twitter poll, Do you see yourself using 3.x in 2017. (是也乎: 当前近6成的人原意升级,不过,真实来也得看项目是否允许了 ) Handling Unicode Strings in Python unicode I am a seasoned python developer, I have seen many UnicodeDecodeError myself, I have seen many new pythonista experience problems related to unicode strings. Actually understanding and handling text data in computer is never easy. Sometimes the programming language makes it even harder. In this post, I will try to explain everything about text and unicode handling in python. (是也乎: 简单的说用 Py3 …可是…唉;-( ) 5 things to watch in Python in 2017 An improved asyncio module, Pyjion for speed, and moving to Python 3 will make for a rich Python ecosystem. (是也乎: 又一个预言术…一切都在 py3 怎么赢得 google 的心了 ) 如何在 Linux 中安装 Scikit-Learn 来我开始机器学习的指南 machine learning In this Tutorial I will describe how you can get started with Machine Learning on Linux using Scikit-Learn and Python 3. 用 pbr 来作 Python 包管理 packaging A library for managing seatuptools packaging needs in a consistent manner. pbr reads and then filters the setup.cfg data through a setup hook to fill in default values and provide more sensible behaviors, and then feeds the results in as the arguments to a call to setup.py - so the heavy lifting of handling python packaging needs is still being done by setuptools. (是也乎: 什么年代了还是 ini 格式…也没有解决包的本地存储管理… ) BDFL 的启源 Guido This is an old article written by Guido van van Rossum himself. Occasionally people ask me about the origins of my nickname BDFL (Benevolent Dictator For Life). At some point, Wikipedia claimed it was from a Monty Python skit, which is patently false, although it has sometimes been called a Pythonesque title. I recently trawled through an old mailbox of mine, and found a message from 1995 that pinpoints the origin exactly. I’m including the entire message here, to end any doubts that the term originated in the Python community. (是也乎: 旧文有回甘… ) Armin 解说 Flask globals - Video flask, video This talk explores how you can build applications and APIs with Flask step by step by being easy to test and scale to larger and more complex scenarios. The talk will also go a bit into the history of some design decisions in Flask and what works well and in which areas you might want to mix it with other technologies for better results. 如何审查 Django ORM SQL 查询 ORM Copy-paste this into your Python 3 interpreter to see a human-readable version of the raw SQL queries that your Django code is running. DSF 宣布2016 Malcolm Tredinnick Memorial Prize 的获胜者 djangogirls Aisha (@AishaXBello) joined the Django community when she attended a Django Girls workshop during EuroPython in 2015. From that point on, Aisha’s trajectory in the Django world was unstoppable. She is not only a talented developer but her desire to keep learning and sharing her knowledge with others is simply inspiring. She organized or helped organize a huge number of Django Girls workshop in her home country of Nigeria. Thanks to her, Nigeria is on its way to be the world-record holder of most Django Girls events organized. (是也乎: 尼日利亚 的 ) Django 或 Flask - Reddit 讨论 flask (是也乎: 也属月经贴了…简单的说, 有銭就上 Django. ) 用NumPy进行通道检测 numpy, scipy Detect lanes on video frames, using NumPy and SciPy. My goal is not to achieve better performance or speed then with OpenCV. Rather, I’m going to implement some techniques learned at the Computer Vision course. (是也乎: OpenCV 也大量使用 Numpy ) Python 机器学习的副作用 machine learning 基于 IP 地址的天气预报 code snippet Jupyter + Pachyderm — 第1部分，探索和了解历史分析 jupyter 第 8 集: Armin Ronacher 谈 Flask，Python生态系统和Unicode podcast 用 Python 从头开始实现分类器令俺明白了什么? machine learning, classification Machine learning can be intimidating for a newcomer. The concept of a machine learning things alone is quite abstract. How does that work in practice ?. In order to demystify some of the magic behind machine learning algorithms, I decided to implement a simple machine learning algorithm from scratch. I will not be using a library such as scikit-learn which already has many algorithms implemented. Instead, I’ll be writing all of the code in order to have a working binary classifier algorithm. The goal of this exercise is to understand its inner workings. (是也乎: 这是理解目标对象的最精确学习方式, 再制丫的. ) 好物 ~ 包/模块/库/片段… ...

原文: Import Python Weekly Newsletter - Issue No 105 欢迎, 来 PyChina/weekly 共同翻译/增订/推荐 周刊 蠎消息 ;-) 该读 ~ 文章, Blog, 教程… 现代字典 ~ Raymond Hettinger : Python core-python, dict Python’s dictionaries are stunningly good. Over the years, many great ideas have combined together to produce the modern implementation in Python 3.6. This fun talk is given by Raymond Hettinger, the Python core developer responsible for the set implementation and who designed the compact-and-ordered dict implemented in CPython for Python 3.6 and in PyPy for Python 2.7. (是也乎: 事实证明一个贴心的数据类型可以增加很多语言的依赖, 但是,另外一个现实也证明了只有一种数据类型的开发语言一样可以很好的使用, 所以? 存乎一心了. ) 通过 SSH 远程运行 Python 3 ssh, click I ran into this situation today where I wanted to issue a few commands over ssh to a remote host as part of a Click command I’m building to do some ops automation here at REVSYS. It’s probably not perfect in terms of error handling, but it sure is simple!. (是也乎: 嗯哼,就是 Fabric3 的软广呗. ) 用 Python 介绍数据科学 - Univeristy of Michigan data science, mooc The course will also introduce data manipulation and cleaning techniques using the popular python pandas data science library and introduce the abstraction of the DataFrame as the central data structure for data analysis. The course will end with a statistics primer, showing how various statistical measures can be applied to pandas DataFrames. By the end of the course, students will be able to take tabular data, clean it, manipulate it, and run basic inferential statistical analyses. (是也乎: 就是 panda 呗… ) 用 Python 进行数据整理 In this post, I will summarize some tidying examples Wickham uses in his paper and I will demonstrate how to do so using the Python pandas library. (是也乎: 依然是 Panda 呢… ) 用 Python 查询和展示天气数据 data science Considering rich Python Ecosystem of tools, libraries, and frameworks for data crunching, I’d like to share a few examples how to plug Datahub API as a data source to your Python-based workflow. I’ll start with a simple example: how to turn Datahub API JSON output into Numpy arrays using Pandas framework. (是也乎: 针对 Datahub API 输出的 JSON ) 2017 放弃 Python 2 python3 Python 3.6.0 came out day before yesterday, and it was like a Christmas present for many of us. But in the midst of all the celebration, many of you were still asking if it is safe to drop Python 2 and move over to Python 3. There still seems to be a fear of missing out on useful third party libraries that lack Python 3 support. So in this post, I will try to settle this issue once and for all by presenting the relevant data. After you have seen all the data, you will be able to come to your own conclusion (I have already expressed my conclusion in the title). (是也乎: 目测嗯哼的… ) 从 Python 到 Numpy numpy There are already a fair number of books about Numpy (see Bibliography) and a legitimate question is to wonder if another book is really necessary. As you may have guessed by reading these lines, my personal answer is yes, mostly because I think there is room for a different approach concentrating on the migration from Python to Numpy through vectorization. (是也乎: 是一部完备的小书…CC 协议,还没有翻译为中文…. rougier/from-python-to-numpy: An open-access book on numpy vectorization techniques, Nicolas P. Rougier, 2017 rST 格式 ) 加速 Python 运行: 案例研究 performance 支持 PyKids 服务 community pykids is a voluntary effort to bring Python to elementary school (5th & 6th grades). At present I run AWS servers to support my venture. These servers are available for anyone to use. I run a monthly bill of about 20 USD to run this server. The money that you donate will go into support keeping these servers online. 为小白的 Python IDE IDE (是也乎: 乱说! 初学更加不应该用 IDE 了… ) 检查 Python 包依赖 dependency (是也乎: 可怕的 Dependencies of django ) 为毛 Python 不是俺的最爱 opinion (是也乎: Python 的目标从来不是最爱哪… ) 好物 ~ 包/模块/库/片段… ...
