For the first part of this tutorial, you'll need a Python 3 interpreter with the sqlite3 standard library module available.
You can run this on your own computer, or use a browser-based environment.
https://pyodide.org/en/stable/console.html will work for a purely browser-based (WebAssembly) environment.
For the second part, you'll also need the ability to pip install Python packages.
Python 3 on your own laptop (maybe in a fresh virtual environment) is a good option here. You could also use GitHub Codespaces or Google Colab or Jupyter Hub or your online notebook solution of choice.
I'll be working through the tutorial using GitHub Codespaces, using https://github.com/github/codespaces-jupyter
