| Excel, Python, and the Future of Data Science
What’s the most widely used tool in data science? Is it pandas or NumPy? Is it the Python language itself? Not really. It’s Excel. You might argue that data scientists aren’t using Excel as their primary tool, and you might be right. But Excel enables non-technical users, like small business owners, to gain insights into their data. In this article, Anaconda CEO Peter Wang discusses his goal of making Python and PyData the “conceptual successor” to Excel.
Practical SQL for Data Analysis
If you need to do some data analysis, what tool do you reach for first? Is it pandas? While pandas is great, it comes with some costs that you might not be aware of, including large memory overhead that can quickly get in the way of your projects. Using databases with SQL can alleviate memory issues. In this tutorial, you’ll learn how to do common data analysis tasks in SQL, which opens the door to mixing SQL and pandas to create lightweight programs that are also fast!

Why Can’t Comments Appear After a Line Continuation Character?
Chaining together many object methods can create long tines that break the PEP 8 79-character line length recommendation. You can use
\ to break the chain of methods onto individual lines, but if you want to leave comments at the end of some of the lines, you’re out of luck. There’s another pattern, though, that solves this.

A Bayesian Analysis of Lego Prices in Python With PyMC3
Follow along with this in-depth analysis of LEGO prices to see Bayesian analysis in action. Along the way, you’ll how pooled and unpooled linear models can be used to determine if a LEGO set is fairly priced. The article is quite technical, so experience with Bayesian statistics is recommended.
How I Teach Python on the Raspberry Pi 400 at the Public Library
Community-based programming courses are a great way to introduce folks to computer programming that otherwise may not have the means to do so. One of the barriers to learning to code is cost. You need a computer to program on, after all. But with the advent of tiny computers like the Raspberry Pi, computers aimed at education are more affordable than ever.
