Many people started switching to Python 3, unfrotunetly most people still write their code like it is Python 2. Below are useful Python 3 features.

A Single Source of Truth for install_requires.

In this blog post I’ll walk through a handful of code smells that indicate you’ve got a class instead of a function, and then follow it up with code examples demonstrating code that exhibits these code smells. Finally, I’ll demonstrate how we might refactor the offending functions into classes.

In this tutorial we will implement basic search in a Django website and touch upon ways to improve it with more advanced options.

All around the country boundaries separate neighborhoods with high and low life expectancy. We used python to find the most extreme examples.

This post talks about reverse engineering the Dropbox client, breaking its obfuscation mechanisms, de-compiling it to Python code as well as modifying the client in order to use debug features which are normally hidden from view. If you're just interested in relevant code and notes please scroll to the end.

It can be hard to get your head around how immense an IoT network deployment is without a map, especially for Smart Cities.  Using HERE XYZ to visualize infrastructure at a city level makes a world of difference.  Let's look at how to do that, first fetching and scrubbing data with Python and then using HERE XYZ with Tangram and a bit of JavaScript to render a web map like the one shown.

How to use Python and Plotly for statistical visualization, inference, and modeling.

FDA drug approvals, legal verdicts, mergers, share buybacks, and the occasional CEO podcast appearance, are all examples of events that impact stock prices.

This post will go through the process of gathering and cleaning this data followed by an exploratory analysis examining price trends and the impact of events on prices.
