Description We built a testing suite, Summit, in Python using Selenium to functionally test our application, the Decisio Health Patient Dashboard. I intend to show how that testing suite got us through the FDA 510(k) clearance process and how to use Selenium and Python to test an application in a ...
Description In this talk we'll discuss how to use pyenv to manage multiple versions of python to allow you to develop and test your code in Python 2, Python 3, pypy, etc.

Description This talk will present an approach to querying data that directly uses some of Python’s most powerful language features, rather than a separate query language like SQL. We’ll show how to persist data in an ordered key-value store and use generators, itertools, and comprehensions to formulate queries. Examples will ...
Description NumPy arrays combine the speed of C with the convenience of Python. It is the fundamental package for scientific and statistical computing in Python.
