Python-digest # 7. News, interesting projects, articles and interviews [December 13, 2013 - December 20, 2013]

Lots of good news and different about Python and life around it. I thank the owlman for his inexhaustible enthusiasm in preparing the illustrations, axce1 for the announcements of articles on Pyramid.

Send links to articles to me in Skype (it coincides with the nickname on Habré), write yourself more about Python. Do not feel sorry for the plus signs (or minus ones) for the digest and actively express your opinion in the comments - this is what serves as an incentive for you to have fresh reading material before every weekend.

I also ask you to take part in the survey regarding the first issue of the 2014 digest. According to the results of the survey in the last issue of the design of the Russian-language articles vs English-language returned to the initial version. Traditions are good, even if they are short-term.
