Python Gets an Event Loop (Again)

March 2014 saw the release of Python 3.4. One of its most notable additions is the inclusion of the new asyncio module to the standard library. The asyncio module is the result of about 18 months of effort, largely spearheaded by the creator of Python, Guido van Rossum, who introduced it during his keynote talk at the PyCon 2013 conference. However, ideas concerning asynchronous I/O have been floating around the Python world for much longer than that. In this article, I’ll give a bit of historical perspective as well as some examples of using the new library.
