Hello friends! I'm looking for a solution to share projects and homework with our students that would allow us to "hide" solutions for exercises. I'm aware of Exercise <http://jupyter-contrib-nbextensions.readthedocs.io/en/latest/nbextensions/ex...> and Exercise2 <http://jupyter-contrib-nbextensions.readthedocs.io/en/latest/nbextensions/ex...> from jupyter extensions (which both look great), but I can't seem to make them work on Azure notebooks. Any ideas? Thanks very much! PS: We're using Azure notebooks so we can get our students up and running without the need of installing Python + jupyter + libraries locally. But maybe there's another choice that would allow us to do this? -- Santiago Basulto.- Co-founder @ rmotr.com
