Let's explore how we can represent a 3D design, display it to the screen, and interact with it, in 500 lines of Python.

Introduction to Natural Language Processing with Python
In this talk, Jess Bowden introduces the area of NLP (Natural Language Processing) and a basic introduction of its principles. She uses Python and some of its fundamental NLP packages, such as NLTK, to illustrate examples and topics, demonstrating how to get started with processing and analysing Natural Languages. She also looks at what NLP can be used for, a broad overview of the sub-topics, and how to get yourself started with a demo project.

Quantitative finance and programming trading strategies w/ Yves Hilpisch, The Python Quants
In this episode, you’ll hear us unpack many subjects related to being a quant and why programming in Python can be a useful skill to have in your toolbox.

Building HTTP 2 server in Python
Python Twisted will support HTTP 2 in its web server. HTTP2 is not available by default, to get it you need to install hyper-h2 (just runpip install twisted[h2]). This is really big and exciting news for whole Python ecosystem so it’s worth seeing how it works and how difficult or easy it is to set up. In this post I’m going to build some simple Twisted website serving content over HTTP 2 and then create a client connecting to this sample site. Will there be any big difference in performance between HTTP 2 and HTTP 1.1? Will my demo site work quicker in HTTP2?

Podcast.__init__ Episode 68 - Test Engineering with Cris Medina
We all know that testing is an important part of software and systems development. The problem is that as our systems and applications grow, the amount of testing necessary increases at an exponential rate. Cris Medina joins us this week to talk about some of the problems and approaches associated with testing these complex systems and some of the ways that Python can help.

Getting Started with Behavior Testing in Python with Behave
Learn how to write behavioral tests for your next Python application using the Behave library.

How does Django’s StreamingHttpResponse work, exactly?
This post tries to explain just what goes on when you use Django’s StreamingHttpResponse. I will discuss what happens in your Django application, what happens at the Python Web Server Gateway Interface (WSGI) layer, and look at some examples.

JupyterDay Atlanta is a locally-organized event that gives Jupyter users, from beginners to experts, the opportunity to meet in person, talk about their work, and write code without leaving their hometown. You’ll get the chance to meet several of Project Jupyter’s core developers in a casual, vendor free zone and participate in an environment filled with education and collaboration.

Austin Python Meetup August 2016 - Austin, TX
For our August meetup, we will have a great talk "Application Security with Python", from Jon Oberheide, who is the co-founder and CTO at Duo. "We all know and love Python for the rapid development of web applications. But how do you scale a codebase, product, and engineering team while developing applications in Python _securely_ without hiring a bunch of appsec experts? This talk will discuss some common frameworks and pitfalls in Python application security, discuss some of our experiences at Duo building security into a Python SDLC, and give an overview of our in-house Python static analysis framework (to be open-sourced RSN)."
