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.

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.

Jupyter Book uses MathJax for typesetting math in your HTML book build.This allows you to have LaTeX-style mathematics in your online content.This page shows you a few ways to control this.

In-line math¶

To insert in-line math use the $ symbol within a Markdown cell.For example, the text $this_{is}^{inline}$ will produce: (this_{is}^{inline}).

Math blocks¶

You can also include math blocks for separate equations. This allows you to focus attentionon more complex or longer equations, as well as link to them in your pages. To use a blockequation, wrap the equation in either $$ or begin statements.

For example,

results in:

[ int_0^infty frac{x^3}{e^x-1},dx = frac{pi^4}{15}]

Latex-style math¶

You can enable parsing LaTeX-style math blocks with the amsmath MyST extension. Enable it by adding the following to _config.yml

Once enabled, you can define math blocks like so:

which results in:

[begin{gather*}a_1=b_1+c_1a_2=b_2+c_2-d_2+e_2end{gather*}]

(2)¶[begin{align}a_{11}& =b_{11}& a_{12}& =b_{12}a_{21}& =b_{21}& a_{22}& =b_{22}+c_{22}end{align}]

Numbering equations¶

If you’d like to number equations so that you can refer to them later, use the math directive.It looks like this:

For example, the following code:

will generate

(3)¶[w_{t+1} = (1 + r_{t+1}) s(w_t) + y_{t+1}]

Alternatively you can use the dollar math syntax with a prefixed label:

which generates

(4)¶[ w_{t+1} = (1 + r_{t+1}) s(w_t) + y_{t+1}]

Note

Labels cannot start with an integer, or they won’t be able to be referenced andwill throw a warning message if referenced. For example, :label:1 and :label:1eq cannotbe referenced.

Linking to equations¶

If you have created an equation with a label, you can link to it from within your text(and across pages!).

You can refer to the equation using the label that you’ve provided by usingthe {eq} role. For example:

results in

A link to an equation directive: (3)
A link to a dollar math block: (4)

labels inside LaTeX environment are not currently identified, and so cannot be referenced.We hope to implement this in a future update (see executablebooks/MyST-Parser#202)!
