Notebooks in QGIS

Finally it’s here: Jupyter notebooks inside QGIS. I don’t know about you but I’ve been hoping for someone to get around to doing this for quite a while.

Qiusheng Wu published the first version of the Notebook plugin on 26 Dec 2025. Late Christmas present?!

For the setup, there’s a handy tutorial by Hans van der Kwast and, additionally, Qiusheng published an intro video:

Development is going fast (version 0.3.0 at the time of writing) so there will be new features when you install / update the plugin compared to both the tutorial and the video.

The user interface is pretty stripped down with just a few buttons to add new code or markdown cells and to run them. And there is a neat drop-down menu with all kinds of ready-made code snippets to get you started:

For other functionalities, for example, to delete cells, you need to right-click on the cell to access the function through the context menu. And, as far as I can tell, there is currently no way to rearrange cells (moving them up or down).

I also haven’t quite understood yet what kinds of outputs are displayed and which are not because – quite often – the cell output just stays empty, even though the same code generates output on the console:

Some of the plugin settings I would have liked to experiment with, such as adjusting the font size or enabling line numbers, don’t seem to work yet. So a little more patience seems to be necessary.

I’ll definitely keep an eye on this one :)

Perché in QGIS manca la funzione Fattoriale

Perché in QGIS manca la funzione Fattoriale

Introduzione

Vi siete mai chiesti perché QGIS, pur avendo un ricchissimo set di funzioni matematiche nel calcolatore di campi, non include la funzione fattoriale? In questo articolo esploreremo le ragioni di questa assenza e scopriremo come implementare facilmente questa funzione quando necessario.

!!! Abstract "La funzione Fattoriale" Il fattoriale di un numero naturale n (indicato con n!) è il prodotto di tutti i numeri interi positivi minori o uguali a n. Ad esempio: 5! = 5 × 4 × 3 × 2 × 1 = 120
