If we want to share our jupyter notebook, but want to hide all messy code behind it, we can use the following command:

Long version:

jupyter nbconvert --to pdf --TemplateExporter.exclude_input=True --TemplateExporter.exclude_input_prompt=True --no-prompt notebook-name.ipynb --output outputfilename

You can change --to pdf to another extension, like --to html or --to markdown.
TemplateExporter only cover some basic setting, so for specific setting each extension see nbconvert docs

Simple version:

jupyter nbconvert --to pdf --no-input --no-prompt notebook-name.ipynb

But before run that command, make sure you already install ipywidget and enable widgetsnbextension

jupyter nbextension enable --py widgetsnbextension
