• 蠎加载百期知识竞赛
  • importpython

It's been 2 years of curating ImportPython and today is the 100th Issue. Wow. What a moment ?. Here is a python quiz competition. Five random() participants who answer all questions correctly win complete bundle of Writing Idiomatic python book by Jeff Knupp. If you take the quiz at the end of it is a link with discount too. This quiz is an our attempt at having fun and saying thanks to all you readers of ImportPython. Do take to twitter with the hashtag #importpython100 happy to hear what you have to say.

(是也乎: 追查了一下, 2014-09-25 开始快译 蠎加载 的, 嗯哼,2012-02-17 开始翻译 蠎周刊 的, 当然 蠎周刊 之前有朋友翻译过前20期,俺是从 77 期开始坚持翻译到 200期,引人了新的快译小伙伴,老高, 然后,重心转移到 蠎加载; 风格也从之前正文的翻译,慢慢变成了主要进行 是也乎 的点评; 不变的是很少有人提交 PR,想来也是因为这种周刊,实在只是个定时 技术新闻点收集, 时效性太强,大家参与进来,并不能获得类似伟大的 字幕组 那种可以长期流传,洗脑天下的乐趣. 之于俺和小伙伴,最大的收获的确也就是:

• 定期翻译,形成周自学节奏
• 了解 Python 领域的主流变化
• 积累 Python 技术演化趋势概念
• 架构选型时帮助扩大思考范围
• ...

简单的说,定期快译一个技术新闻周刊,是种非常好的强迫自学的形式; 并不特别强烈的建议大家都来加入这种自学,毕竟太散了... 但是,的确是一个有效无意识提高领域技术语感的好形式.

• Patrick Kennedy: Flask 应用的单元测试
  • testing, flask

This blog post provides an introduction to unit testing a Flask application. I’ve been on a big unit testing kick at work recently which is spilling over into updating the unit tests for my personal projects. Therefore, I thought it would be a good time to document the basics of unit testing a Flask application.

• 定义过滤器和有序字典
  • django, python3

This week I ran into a minor problem that took a surprising amount of time to resolve. Getting a Django template to produce a dict in sorted order. While there were answers out there, none seemed to match the environment that I am using (python 3, Django 1.10). After some experimentation, I finally came up with what I think is a good solution.

(是也乎:

Django 中的模板看起来什么都能作,其实... )

• 针对 Python 3 的案例
  • python3

"There is high probability that Python 3 is such a failure it will kill Python" - Zed Shaw. As Curator of a Python Newsletter for 2+ years I can tell you at-least 20-30% of all articles I read of late have code written only for Python 3. Just recently I was at Pycon India and met lot of student who never wrote a single line in 2.x. Startup founders starting with new development choosing Python 3. Lot of people are sleeping on Python 3. A year more and hopefully everyone will be awake.

• 在 Django 网站上水印图像
