## What is Carnets?

Jupyter notebooks are a powerful tool used in education and research. You can write small snippets of Python code and observe the result on screen, combine with paragraphs of text, using Markdown.

Carnets provides a complete, stand-alone, implementation of Jupyter notebooks. Everything runs on your device, using the embedded Python interpreter; you do not need an internet connection. You can chose between Jupyter notebooks and the more advance Jupyterlab using Settings.

Numpy, Sympy, Matplotlib, Pandas, lxml, bokeh, nbextensions (including ipywidgets) and many other packages are pre-installed. To see the full list of installed packages, type "%pip list" in a code window. You can add more packages using "%pip install packageName", but only if they are pure Python.

If you need scipy, seaborn or scikit-learn, please use our other App, "Carnets - Jupyter (with scipy)".

You can share your notebooks with other apps and also open notebooks or directories managed by other apps. 

Partial list of installed packages: astropy, babel, bokeh, cryptography, cvxopt, Fiona, geopandas, geopy, lxml, matplotlib, numpy, openCV, pandas, pillow, pyFFTW, pyproj, rasterio, regex, shapely, sympy, wordcloud.

### 5/5 — Add other files to be run.

*2026-06-28, version 1.9.1*

It is a good app for writing the codes of python. It should also be made for to write the code such as html , js, css and etc languages. And where we write code in the box that should be changed into normal just like vsc.After that very thing is fine. I wish that the dev of this app should understand the perception of collage student or data science student who are going to do jobs after completing their studies using a very good app for the students who are using iPadOS.
