Python 3.13.5 : use the jupyterlab, notebook and voila - part 001.

JupyterLab is the latest web-based interactive development environment for notebooks, code, and data. Its flexible interface allows users to configure and arrange workflows in data science, scientific computing, computational journalism, and machine learning. A modular design invites extensions to expand and enrich functionality.

Let's test with these python modules: jupyterlab, notebook and voila.

First, I install with pip tool the jupyterlab python module:

pip install jupyterlab
Collecting jupyterlab

Next, the install of the notebook python module

pip install notebook
Collecting notebook
...
Installing collected packages: notebook
Successfully installed notebook-7.4.4

This python package named voila will help us to use online graphic user interfaces:

pip install voila
Collecting voila
...
Successfully installed voila-0.5.8 websockets-15.0.1

The voila package need to work with ipywidgets python package:

pip install ipywidgets
Collecting ipywidgets
...
Successfully installed ipywidgets-8.1.7 jupyterlab_widgets-3.0.15 widgetsnbextension-4.0.14

Let's start the jupiter tool with this command:

jupyter notebook

I used an default python example with a slider:

import ipywidgets as widgets
from IPython.display import display

slider = widgets.IntSlider(value=5, min=0, max=10)
display(slider)

This command will start the web with the slider using the voila command:

voila test.ipynb

The result is this:
