Our guests this week, Matthew Rocklin and Alexander Schepanovsky, help us understand all of that and more. Matthew and Alexander have each created their own Python libraries to make it easier to employ functional paradigms in your Python code. In this episode they help us understand the benefits that functional styles can have and the benefits that can be realized by trying them out for yourself.</p> <h3>Brief Introduction</h3> <ul> <li>Hello and welcome to Podcast.__init__, the podcast about Python and the people who make it great.</li> <li>Subscribe on <a href="https://itunes.apple.com/us/podcast/podcast.-init/id981834425?mt=2&uo=6&at=&ct=&utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">iTunes</a>, <a href="http://www.stitcher.com/s?fid=64838&refid=stpr&utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Stitcher</a>, <a href="http://tunein.com/embed/follow/p726240/#?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">TuneIn</a> or <a href="https://www.pythonpodcast.com/feed/mp3/?utm_source=rss&utm_medium=rss">RSS</a></li> <li>Follow us on <a href="https://twitter.com/Podcast__init__?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Twitter</a> or <a href="https://plus.google.com/+Podcastinit-the-python-podcast?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Google+</a></li> <li>Give us feedback!

Are they distinct enough from each other that it would make sense to use them both in a single project? – Tobias</li> <li>What inspired each of you to create your respective libraries? – Tobias</li> <li>There is a functools module in the Python standard library that provides some methods that enable functional paradigms. Where does that module fall short and how do your respective libraries augment or replace the functionality in that module? – Tobias</li> <li>There is also a library named fn.py which provides functional paradigms for use in Python. Can you each compare and contrast it with your own work? – Tobias</li> <li>There are a number of concepts involved in functional programming such as currying, function composition, immutable data, and pure functions. Can you describe some of those concepts and then explain which of them you tried to incorporate into your libraries? – Tobias</li> <li>What are some of the resources that you have found to be most helpful when trying to learn and apply functional principles to your programs? – Tobias</li> </ul> <h3>Keep In Touch</h3> <ul> <li>Alexander <ul> <li><a href="https://twitter.com/hackflow?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Twitter</a></li> <li><a href="http://hackflow.com?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Blog</a></li> </ul> </li> <li>Matthew <ul> <li><a href="http://matthewrocklin.com?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Website</a></li> <li><a href="http://toolz.readthedocs.org?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Toolz</a></li> <li><a href="https://twitter.com/mrocklin?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Twitter</a></li> <li><a href="https://github.com/mrocklin?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">GitHub</a></li> </ul> </li> </ul> <h3>Picks</h3> <ul> <li>Tobias <ul> <li><a href="https://www.datadoghq.com?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">DataDog</a></li> </ul> </li> <li>Alexander <ul> <li><a href="http://www.syfy.com/theexpanse?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">The Expanse</a></li> <li><a href="https://revolut.com/?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Revolut</a></li> </ul> </li> <li>Matthew <ul> <li><a href="http://riemann.io?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Riemann</a></li> <li><a href="http://www.fivedancesthemovie.com/?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Five Dances</a></li> <li><a href="http://distributed.readthedocs.org/en/latest/?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Distributed</a></li> </ul> </li> </ul> <h3>Links</h3> <ul> <li><a href="http://rosettacode.org/wiki/Rosetta_Code?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Rosetta Code</a></li> <li><a href="http://toolz.readthedocs.org?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">PyToolz</a></li> <li><a href="http://funcy.readthedocs.org/en/stable/?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Funcy</a></li> <li><a href="https://github.com/kachayev/fn.py?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Fn.py</a></li> <li><a href="https://github.com/lihaoyi/macropy?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">MacroPy</a></li> <li><a href="https://github.com/llllllllll/codetransformer?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Code Transformer</a></li> <li><a href="http://www.infoq.com/presentations/Simple-Made-Easy?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">Simple Made Easy by Rich Hickey</a></li> </ul> <p>The intro and outro music is from Requiem for a Fish <a href="http://freemusicarchive.org/music/The_Freak_Fandango_Orchestra/?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">The Freak Fandango Orchestra</a> / <a href="http://creativecommons.org/licenses/by-sa/3.0/?utm_source=rss&utm_medium=rss" rel="noopener" target="_blank">CC BY-SA</a><img alt="" height="0" src="https://analytics.boundlessnotions.com/piwik.php?idsite=1&rec=1&url=https%3A%2F%2Fwww.pythonpodcast.com%2Fepisode-46-functional-python-with-matthew-rocklin-and-alexander-schepanovsky%2F&action_name=Functional+Python+with+Matthew+Rocklin+and+Alexander+Schepanovsky+-+Episode+46&urlref=https%3A%2F%2Fwww.pythonpodcast.com%2Ffeed%2F&utm_source=rss&utm_medium=rss" style="border: 0; width: 0; height: 0;" width="0" /></p>
