The Mercury is a new framework for converting Jupyter Notebook to a web app. The widgets are constructed based on the YAML config (similar to R Markdown). The user can tweak the values of the widgets and execute the notebook from the top to the bottom. The notebook sharing is as simple as sending a link. What is more, you can decide whether to show or hide the code. In the talk, I would like to show how the Python notebook can be converted to a web app and deployed to the cloud.
