As someone who often works with Python scripts, Jupyter Notebook is my favorite tool for making notes during lectures and sharing my painstakingly-written code with my programming friends and rivals.

Google Colab makes it easy to write and execute Python code online. If you want to save your Colab notebook to Github, follow these steps.

Jupyter Notebook lets you author visualizations, but also share them and allow interactive changes to the shared code and data set. Code sharing.

Add-on to Jupyter Notebooks enables a literate Python development style that gives you high-quality documentation, tests, continuous integration, and packaging for free.

Because of the client/server architecture, it is very simple to share notebooks with other users. You can — in theory — use Jupyter for anything you could use Python for.
