Retool Workflows is a fast way to build and automate recurring cron jobs, custom alerts and ETL jobs. Stop provisioning infrastructure and maintaining one-off scripts.

Code level control when you need it, GUI when you don’t.

News

Now C/C++ isn't the only game in town with Arduino partnering with Damien George for official MicroPython firmware on selected board models.

Articles, Tutorials and Talks

In this tutorial, you will discover how to change a nested for-loop to be concurrent or parallel in Python with a suite of worked examples.

This article explains the new features in Python 3.12, compared to 3.11.

There are plenty of ways to measure the speed of your code. Let me show you a few that I considered for the Writing Faster Python series.

Python 3.11 only made one change to unittest, but it’s a good one: context manager methods. These methods can simplify setup and teardown logic in many cases, such as dynamic use of unittest.mock. In this post we’ll look at a couple fo examples using the new methods, and a backport you can copy-paste into your projects, in plain and Django flavours.

This post will cover just one tiny piece of Python packaging’s complexity: the CPython stable ABI. We’ll see what the stable ABI is, why it exists, how it’s integrated into Python packaging, and how each piece goes terribly wrong to make accidental ABI violations easy.

If you’re using NumPy, Polars, Zarr, or many other libraries, setting a single environment variable or calling a single API function might make your code run 20%-80% faster. Or, more accurately, it may be that your code is running that much more slowly than it ought to. The problem? A conflict over who controls parallelism: your application, or the libraries it uses. Let’s see an example, and how you can solve it.

In this video I go though how I setup my operating system to code for datascience. We talk about operating system, terminal, IDEs and more.

Learn about this rapidly developing capability.

In Python?!! That’s right, and it’s pretty painless with PyScript.
