Python-digest # 23. News, interesting projects, articles and interviews [April 13, 2014 - April 20, 2014]

Another selection of news, articles and interesting projects from the world of python and nearby technologies arrived. The main news, perhaps, can be called just a gorgeous selection of videos from the conference PyCon 2014, which itself is capable of captivating for many hours. But other materials are quite decent. Do you want python 2.8?



Thanks a lot to owlman75 - despite the fact that he didn’t have time to draw a thematic illustration - he was very responsible and professional in his work, having completed the illustration in advance. Many thanks to those who send news. If it is not difficult for you - subscribe - I will show who exactly sent this or that news - the people should know their heroes.

  asyncio does not know how to work with HTTP.

  asyncio will never become a web server. It was made exactly as an event loop for tcp, ssl, unix sockets, pipes, and subprocesses. Plus streaming API.
  
  The web was deliberately drunk and now what was in aiohttp. This part is simply not ripe for inclusion in the standard library.
