Python-digest # 26. News, interesting projects, articles and interviews [May 4, 2014 - May 11, 2014]

Another news release, articles links to interesting projects on python and about python-related topics. This time about dynamic programming, apples and bananas, subway and even yaks. In general, I hope you enjoy it, despite the fact that this week was not very rich in news.

I express my traditional gratitude to owlman75 for the release. And just a huge thank you to axce1 - I finally put in his changes regarding the rss import and now the probability that I will miss interesting news in particular from Planet python tends to zero.

Please send me your news / corrections / suggestions, and if you want to participate in creating a digest and release me from monitoring a particular direction, you can even knock on Skype to knock me out: alrusdi
