Python-digest # 17. News, interesting projects, articles and interviews [March 2, 2014 - March 9, 2014]

Today, news about python and nearby technologies turned out to be quite enough. Many thanks to those who send new articles to the tool for creating digests . It looks like the project is starting to move in the right direction.

The illustration from owlman75 is exclusive today - I had to draw it from home by hand. In my opinion, she only benefited from this. In any case, thank you so much to the author.

I also want to congratulate all the girls and women on the last holiday. Let the holidays take place in the calendar, but in the soul remain forever.
