Pessoal,
se quiser usar “Collapsable / expandable jupyter cells” em seus jupyter notebooks como os do @jeremy, instale a extensão ‘collapsible headings’ : https://github.com/ipython-contrib/jupyter_contrib_nbextensions
Passo-a-passo num Terminal :
-
Download :
pip install https://github.com/ipython-contrib/jupyter_contrib_nbextensions/tarball/master -
Install :
jupyter contrib nbextension install --user -
Enable :
jupyter nbextension enable collapsible_headings/main
That’s it ! 
Pode rodar o seu jupyter notebook agora
