Jupyter Notebooks as Markdown Documents, Julia, Python or R Scripts¶
Have you always wished Jupyter notebooks were plain text documents? Wished you could edit them in your favorite IDE? And get clear and meaningful diffs when doing version control? Then… Jupytext may well be the tool you’re looking for!
Jupytext is a plugin for Jupyter that can save Jupyter notebooks as either
Common use cases for Jupytext are:
Doing version control on Jupyter Notebooks
Editing, merging or refactoring notebooks in your favorite text editor
Applying Q&A checks on notebooks.
You can install Jupytext with
pip install jupytext
conda install jupytext -c conda-forge.
Then, restart your Jupyter server (for more installation details, see the install section in the documentation).
When Jupytext is installed,
.md files have a notebook icon. And you can really open and run these files as notebooks
The most convenient way to use Jupytext is probably through paired notebooks.
To pair a given
.ipynb or text notebook to an additional notebook format, use either
jupytext at the command line
jupytext --set-formats ipynb,py:percent notebook.ipynb
see the documentation.
or a local or global
jupytext.toml configuration file.
with e.g. the following content:
default_jupytext_formats = "ipynb,py:percent"
see the documentation.
When you save a paired notebook in Jupyter, both the
.ipynb file and the text version are updated on disk.
When a paired notebook is opened or reloaded in Jupyter, the input cells are loaded from the text file, and combined with the output cells from the
You can edit the text representation of the notebook in your favorite editor, and get the changes back in Jupyter by simply reloading the notebook (Ctrl+R in Jupyter Notebook, ”reload notebook” in Jupyter Lab). And the changes are propagated to the
.ipynb file when you save the notebook.
Alternatively, you can synchronise the two representations by running
jupytext --sync notebook.ipynb at the command line.
Which text format?¶
Jupytext implements many text formats for Jupyter Notebooks. If your notebook is mostly made of code, you will probably prefer to save it as a script:
Use the percent format, a format with explicit cell delimiters (
# %%), supported by many IDE (Spyder, Hydrogen, VS Code, PyCharm and PTVS)
Or use the light format, if you prefer to see fewer cell markers.
If your notebook contains more text than code, if you are writing a documentation or a book, you probably want to save your notebook as a Markdown document
Use the Jupytext Markdown format if you wish to render your notebook as a
.mdfile (without its outputs) on GitHub
Use the R Markdown format if you want to open your Jupyter Notebooks in RStudio.
