voila

Voila is a French interjection used to call attention to something that has just been presented or accomplished, roughly equivalent to there it is or here you go. It is commonly used when delivering results, solutions, or a finished item, and in English it is often used as a loanword to announce the completion of a task or the presentation of an object.

Origin and spelling: The word comes from the French voir (to see) combined with là (there). The standard spelling is voilà, with a grave accent on the final a, and it is pronounced roughly as "vwah-lah." In writing, English speakers frequently use voilà to punctuate a successful reveal or delivery.

Voila in computing: Voila is also the name of an open-source Python library that turns Jupyter notebooks into standalone, interactive web applications. It is part of the Jupyter ecosystem and renders notebooks as dashboards or reports without exposing the underlying code cells. Interactive controls are provided by ipywidgets, allowing users to manipulate the displayed outputs. Voila is typically installed with pip install voila and run from the command line as voila notebook.ipynb. Deployments can be hosted via JupyterHub, Binder, or traditional web servers, and the tool supports templates and customization to tailor the user interface.

See also: As a loanword, voilà appears across many languages to signal a successful presentation. In technology, the Voila project represents one approach to turning exploratory notebooks into user-friendly applications suitable for non-programmer audiences.
