Basic Cheat Sheet for Python (PDF, Markdown and Jupyter Notebook) 100-plus-Python-programming-exercises-extended. 1 1,317 6.5 Jupyter Notebook. Furthermore, you learned that in a Jupyter Notebook file, you can double-click in any Markdown cell to see the syntax, and then run the cell again to see the Markdown formatting. Note: if you type text in a Markdown cell with no additional syntax, the text will appear as regular paragraph text.

The Python Markdown extension allows displaying output produced by the current kernelin markdown cells. The extensions is basically agnostic to the kernel language, however mosttesting has been done using Python.

For example:If you set variable a in Python

and write the following line in a markdown cell:

It will be displayed as:

The notebook needs to be trusted in order to execute Python commands in markdown.This is indicated by the “trusted” check mark:

If you see the “unstrusted” question mark, use File->Trust Notebook in the menu.

Caution: If you trust a notebook, you allow it to execute any code that is contained between the {{...}}curly braces on your notebook server.

Before rendering the markdown cell:

After rendering the markdown cell:

Code is only executed when the notebook is trusted. So if your original code is shown asrendered markdown output, please make sure your notebook is trusted. You can check if the notebookis trusted by looking at the check mark at the top of the window.

Caution: There is no restriction in the expression you can embedd between the curly braces {{}}.Be careful as you might crash your browser if you return too large datasets, or worse.

Exporting¶

In order to have nbconvert show the computed output when exporting to another format,use the pre_pymarkdown.py preprocessor. If you used the pythonsetup.pyinstall command to install theIPython-contrib extension package, this will already be installed.

For manual setup, you need to copy this file to a location within the Python path (or extend PYTHONPATH).Additionally, you need to add these two lines to your jupyter_nbconvert_config.py configuration file:

Internals¶

The extension overrides the textcell.MarkdownCell.prototype.render function and searches for the expression enclosedin double curly braced {{<expr>}}. It then executes the expression and replaces it with the result returned fromthe running kernel, embedded in a <span> tag.Additionally, the result is saved in the metadata of the markdown cell, i.e. cell.metadata.variables[varname].This stored value is displayed when reloading the notebook and used for the nbconvert preprocesser.

The preprocessor pre_pymarkdown.PyMarkdownPreprocessor allows nbconvert to display the computed variableswhen converting the notebook to an output file format.

Unfortunately, embedding in LaTeX is not supported currently, as computing expressions between the curly bracesand rendering LaTeX equations is happening asynchronously, and it is difficult to handle this in a consistent way.Ideas or pull request to implement this functionality are welcome.
