Markdown Cell Jupyter

Posted on by admin

Jupyter Notebook is a great tool for data analysis. And one of its greatest features is that you can easily combine runnable code with rich-text annotations. Markdown cells that contain such annotations support both HTML and Markdown syntax.

Personally I prefer # Header (markdown syntax) to <h1>Header</h1> (HTML syntax) in my notebook’s cells as the former looks more human. So I use markdown syntax more often and a concise cheat sheet for Jupyter Notebook markdown is what I was missing for a long time. Yes, I’m aware of such comprehensive cheat sheets like this and this, they are great but too verbal and it’s hard to print them on one page to have it easily accessible.

The sections below describe how to hide each using cell tags in MyST Markdown. If you’re working with.ipynb files, see the cell tags guide on adding cell tags to notebooks in Jupyter Notebook or JupyterLab. If an element is hidden, Jupyter Book will display a small button to the right of the old location for the hidden element. In the Jupyter Notebook, there is a speciall “Attachments” cell toolbar which you can use to see all attachments of a cell and delete them, if needed. HTML Elements (HTML only) § It is allowed to use plain HTML elements within Markdown cells. Oct 04, 2019 Normally in Jupyter Notebook, the cell type will be code by default. If we want to enter any text to describe anything or something not to be considered as code then we need to use the cell type as Markdown. To convert a code cell to markdown cell we can change the cell type from toggle toolbar or cell menu with keyboard shortcut M.

Eventually, I decided to gather all crucial points of the markdown syntax that are actual for Jupyter notebook and combine them in a concise cheat sheet that I present to you. It doesn’t explain much but should be useful if you simply forgot something. Click the picture to download the PDF version.

I didn’t get into the details of LaTeX syntax (see the penultimate cell in the cheat sheet with the square root of k) since it’s well described here (get ready, it’s a very long document) and you can even download a pretty good cheat sheet here.

It is possible to store Jupyter notebooks in plain Markdown. This allows youto define a notebook structure entirely using MyST Markdown. For more informationabout MyST Markdown, see MyST Markdown overview.

Notebooks with Markdown can be read in, executed, and cached by Jupyter Book (see Execute and cache your pages for information on how to cache pages).This allows you to store all of your notebook content in a text format that is much nicer for version control software, while still having all the functionality of a Jupyter notebook.


MyST notebooks uses [MyST-NB to convert between ipynb and text files][myst-nb:index].See its documentation for more information.

To see an example of a MyST notebook, you can look atmany of the pages of this documentation.For example, see ../interactive/ and ../content/


Create a MyST notebook with Jupytext¶

The easiest way to create a MyST notebook is to use Jupytext, a toolthat allows for two-way conversion between .ipynb and a variety of text files.

You can convert an .ipynb file to a MyST notebook with the following command:

A resulting file will be created.This can then be used as a page in your book.


For full compatibility with myst-parser, it is necessary to use jupytext>=1.6.0.

Jupytext can also automatically synchronize an .ipynb file with your Markdown.To do so, use a Jupyter interface such as Jupyter Lab or the classic notebook interfaceand follow the Jupytext instructions for paired notebooks.


Convert a Markdown file into Jupytext MyST Markdown¶

Jupyter Book has a small CLI to provide common functionality for manipulating andcreating MyST Markdown files that synchronize with Jupytext. To add Jupytext syntaxto a Markdown file (that will tell Jupytext it is a MyST Markdown file), run thefollowing command:

If you do not specify --kernel, then the default kernel will be used if there isonly one available. If there are multiple kernels available, you must specify onemanually.

Structure of MyST notebooks¶

Let’s take a look at the structure that Jupytext creates, which you may also useto create a MyST notebook from scratch. First, let’s take a look at a simple MyST notebook:

There are three main sections to notice:

Frontmatter YAML¶

MyST notebooks need special frontmatter YAML to tell Jupytext that theycan be converted to .ipynb files. The frontmatter YAML block

tells Jupytext that the file is in myst format, and that its code shouldbe run with a Python 3 kernel.

Code cells¶

Code blocks in MyST notebooks are defined with the following MyST directive:

You can optionally add extra metadata to the code cell, which will be convertedinto cell metadata in the .ipynb file. For example, you can add tags to your codecell like so:

You may also explicitly pass the kernel name after {code-cell} to make it clear whichkernel you are running. For example:

However, remember that there is only one kernel allowed per page.

Markdown content¶

Everything in-between your code cells is parsed as Markdown content using theMyST Markdown parser. See MyST Markdown overview formore information about MyST Markdown.

To explicitly split up Markdown content into two Markdown cells, use the followingpattern:

You may also attach metadata to the cell by adding a Python dictionary after the +++.For example, to add tags to the second cell above:


Please note that cell breaks and metadata specified in MyST files via the +++ syntaxonly propagate to their .ipynb counterpart. When generating the book’s HTML, Markdowncell information is discarded to avoid conflicting hierarchies in the structure of thedocument. In other words, only code cell tags have an effect on the generated HTML.
