Sev Leonard: Object Oriented Data Science in Python

Hosted by Portland Data Science Group

Public group


A lot of focus in the data science community is on reducing the complexity and time involved in data gathering, cleaning, and organization. In this talk Sev Leonard will discuss how object oriented design techniques from software engineering can be used to reduce coding overhead and create robust, reusable data acquisition and cleaning systems. Sev will provide an overview of object oriented design and walk through an example of using these techniques for getting and cleaning data from a web API in Python. You can find the Jupyter Notebook for this talk on Github ( This talk is based on Sev's recent ODSC article (

For a more in depth treatment of the subject see Sev's tutorial on object oriented data pipelines from PyCon 2016 on YouTube ( and GitHub (
