-Note that SoS recognizes the [`%expand` magic](https://vatlab.github.io/sos-docs/doc/documentation/SoS_Magics.html#magic_expand) and highlights the intepolated expressions. SoS essentially treats the cell content as [Python f-strings](https://www.python.org/dev/peps/pep-0498/) (with configurable sigil) so almost arbitrary Python expressions could be used. In addition, instead of passing variables from subkernels to SoS and to a markdown cell, you can use a [`%render` magic](https://vatlab.github.io/sos-docs/doc/documentation/SoS_Magics.html#magic_render) to render output from any subkernels as markdown.
