Can I defer a python code block execution?

[Gautzilla]

Description

I'm working on a presentation using Quarto with a revealjs export.

I'm showcasing some features that manipulate files on disk, and wanted to execute a code block on-demand (that is when I reach the relevant slide), however all code block within the document are ran when the kernel is started:

Starting python3 kernel...Done

Executing 'presentation_osekit.quarto_ipynb'
  Cell 1/1: ''...Done

Is there a way to manually run code blocks? I'm playing with the pyodide extension but I'm struggling installing my package with micropip.

Thanks!!

See the following Quarto extension: https://github.com/coatless-quarto/pyodide

Making my own publicity:

• You can check for more than two hundred extensions at http://m.canouil.dev/quarto-extensions/
• You can search and install them directly from VSCode/Positron via the Quarto Wizard extension: https://github.com/mcanouil/quarto-wizard

Thanks a lot!

As I mentioned, I was already playing with pyodide and trying to get my package installed within it, but now that I am confident this is the way to go, I'll dive deeper in it.

To be clear, all computations happen nearly at the first step of rendering to static files.
So, the only way to make something live is to use something with browser integration like WASM.

OK, thank you so much for the answers!
