I wrote an article about different ways how to hide code in Jupyter Notebook. According to my findings, there are several ways in which this can be done.

1. Hide all code in nbconvert

When exporting notebook with nbconvert you need to add --no-input in the command:

Copyjupyter nbconvert --to html --no-input your-notebook.ipynb

2. Hide selected cells

You can hide selected cells by adding a tag hide_code, like in the animation below:

The command that hide code only for selected cells:

Copyjupyter nbconvert --to html --TagRemovePreprocessor.remove_cell_tags='{"hide_code"}' my-notebook.ipynb

3. Export to HTML with Mercury

The Mercury is an open-source for sharing notebooks with non-technical users. It can hide code. It can also generate widgets for the notebook that are connected with variables in the code. The notebook export process is controlled with YAML header, below is the example YAML that hides the code:

Copy---
title: My notebook
description: My amazing notebook with hidden code
show-code: False
---

The example notebook with YAML header:

The HTML (website) generated for the notebook with Mercury:

I was seeking the same question in SO and finally turned out to a very straightforward way:

Assuming using Firefox(57) + Win7

1. Run Jupyter notebook and download the notebook in the browser: File->Download as->HTML and you will get a html page with code and output.
2. Open the exported HTML with browser and activate the browser console with key F12

3. Run following command in the console:

   document.querySelectorAll("div.input").forEach(function(a){a.remove()})
   

4. The code removes all input div DOM. Then right mouse button and chose "Save Page As" and Save the "Complete page" (not single page).

5. You will get a page with an associated folder in windows. Use a trick by zip the html page and then extract to unbind the associated. The folder is useless.

6. Now it is a single html page without code. You can re-distribute it or print it as PDF.

If you are not using Firefox or Windows, please adjust the above 3-6 steps.

Make sure you are working with Qt Console (anaconda):

Install Jupiter extensions:

!pip install jupyter_contrib_nbextensions

!jupyter contrib nbextension install --user 

Enable nbextension:

!jupyter nbextension enable codefolding/main

Install pyppeteer:

!python -m pip install -U notebook-as-pdf

!pyppeteer-install

MAKE SURE YOUR WORKING DIRECTORY IS WHERE YOUR Untitled.ipynb FILE IS SAVED Save file to HTML format without codes:

!jupyter nbconvert Untitled.ipynb --no-input --no-prompt --to html

EXPORT TO PDF FORMAT:

!jupyter-nbconvert Untitled.ipynb --no-input --no-prompt --to pdfviahtml

PS. Exporting HTML and PDF format are mutually exclusive commands, you can use either.

Yes you can and it's quite easy and a built in feature

Copyjupyter nbconvert --to html notebook.ipynb

That will generate a notebook.html file. Output can be customized. Also check out the slideshow functionality (View>Cell-Toolbar>Slideshow) which can also be used with nbconvert.

Also the notebook.ipynb Jupyter file can be uploaded to Github where the current version gets rendered. Depending on what you want that information might be useful too

Also check out line/cell magic. You can run bash commands directly in your jupyter cell like so:

Copy%%bash
convert graphviz/MyPic.jpg -resize 70% graphviz/MyPic_sm.jpg
