Hey guys, this is Ankur. Curator behind ImportPython. Will be attending PyconIndia. Happy to meet you all and discuss all things Python. Get your opinion on the newsletter, How to make it better ?. Ping me on ankur at outlook dot com or just reply to this email. I will respond back. See you there.


Ankur 就是 ImportPython 的作者,原来是 印度人... )

asynq is a library for asynchronous programming in Python with a focus on batching requests to external services. It also provides seamless interoperability with synchronous code, support for asynchronous context managers, and tools to make writing and testing asynchronous code easier. asynq was developed at Quora and is a core component of Quora's architecture. See the original blog post here.


嗯哼, 又一个没有进入 build-in 的优秀模块


其实,公司想成名, 将公司名嵌入到著名的开源模块中,一直是非常好的渠道. )

There have been a few recent articles reflecting on the current status of the Python packaging ecosystem from an end user perspective, so it seems worthwhile for me to write-up my perspective as one of the lead architects for that ecosystem on how I characterise the overall problem space of software publication and distribution, where I think we are at the moment, and where I'd like to see us go in the future.


少见的长篇大论, 追根溯源 Python 包管理的的历史和发展; 这已经不是头一家从根儿上重构 py 包发行机制的尝试了. 当然, 事实也证明, 从一开始不完美的事物,往往能在其后发展出创始人也无法想象的花活儿来. 参考 JavaScript ... 嗯哼, 那个连姓名都故意乱起的语言. )

This team is responsible for supplying a variety of web apps built on a modern stack (mostly Celery, Django, nginx and Redis), but have almost no control over the infrastructure on which it runs, and boy, is some of that infrastructure old and stinky. We have no root access to these servers, most software configuration requires a ticket with a lead time of 48 hours plus, and the watchful eyes of a crusty old administrator and obtuse change management process. The machines are so old that many are still running on real hardware, and those that are VMs still run some ancient variety of Red Hat Linux, with, if we’re lucky, Python 2.4 installed.


就是上篇文章的另外一个分支, 分享 PayPal 的折腾成果. )

The notebook functionality of Python provides a really amazing way of analyzing data and writing reports in one place. However in the standard configuration, the pdf export of the Python notebook is somewhat ugly and unpractical. In the following I will present my choices to create almost publication ready reports from within IPython/Jupyter notebook.


讲真, 每次见到这么细心的一点点解决 LeTaX 和现实世界结合的分享, 就看见了20年前的 王珢 孤独的宣传 Emacs+TeX 的身影 )

Paul Bailey, "A Guide to Bad Programming", at PyBay2016 was my fav talk amongst all. Check out the youtube channel.


哈! 其实烂代码指南比好代码手册,要更加有用的. )

I wrote a program to clean up scans of handwritten notes while simultaneously reducing file size. Some of my classes don’t have an assigned textbook. For these, I like to appoint weekly “student scribes” to share their lecture notes with the rest of the class, so that there’s some kind written resource for students to double-check their understanding of the material. The notes get posted to a course website as PDFs.

简单的说,经过复杂的处理,终于可以免去重新用电脑整理课堂笔记的事儿了! 大体积的扫描件经过处理,就能变成又小又清晰的 pdf 来卖了!


This tutorial will show you how to transform an image with different filters and techniques to deliver different outputs. These methods are still in use and part of a process known as Computer-To-Plate (CTP), used to create a direct output from an image file to a photographic film or plate (depending on the process). Note - It's a pretty good article that makes uses of Python 3, Pillow and is well written.


WoW 强烈历史感的科普文, 将出版的图像处理和 python 的结合聊明白了.
