Python-digest # 5. News, interesting projects, articles and interviews [November 29, 2013 - December 6, 2013]

We continue to find the most interesting and useful news. This week was pretty boring, but we still dug out a decent amount of interest. I was pleased with a small surge in the number of articles in the right hub. Thanks to owlman , we have timely notification of the upcoming meeting of pythonists at the Mailru Group, an illustration of the digest, and the announcement of the chronic library. Thank you very much for this!

In addition, the axce1 habrauser continues to develop our tool for creating digests. This week a simple search on the tape appeared in it. He is also no less thankful to you and I ask you to support him with pluses into karma, since the very existence of this digest depends largely on this tool; its development has stimulated me very much to find and announce more useful information about Python for you.
