Positron IDE: A Hands-on Python Tutorial

By · Published by Everything Blog

In short

Built on Visual Studio Code's open-source architecture, Positron provides dedicated data science features such as the Data Explorer for spotting data quality issues and the Posit Assistant for AI-driven visualizations and analyses. A practical Python exercise walks users through analyzing 5,130 fictional sales orders to clean data and compare retail versus wholesale median order values across scripts and notebooks. The environment integrates directly with the uv package manager, allowing developers to manage dependencies, generate lock files, and initialize virtual environments using the Command Palette. Windows systems require the latest Visual C++ Redistributable, and users should prepare…

Data analysis often starts with an unfamiliar spreadsheet or CSV file. Before you can write a single transformation, you need to know what’s in it and what’s wrong with it. Positron is a free IDE for data science projects that puts that inspection step in the same workspace as your code, so you can examine the data first and then watch your results take shape as you run your code.

In this tutorial, you’ll use Positron’s data tools to answer one question about a set of sales orders: How does median order value differ between retail and wholesale orders across product categories? You’ll inspect the raw data, clean it in a script, repeat the analysis in a notebook, and try Positron’s AI assistant. Then you’ll decide whether the tool fits the way you and your team work with data.

By the end of this tutorial, you’ll understand that:

- Data Explorer helps you find quality issues in your data before running cleanup steps in Python.

- Data cleaning belongs in saved code, whether that’s a script or a notebook, so…
