With Jupyter Notebook integration available in DataSpell , you can easily edit, execute, and debug notebook source code and examine execution outputs including stream data, images, and other media. 
Notebook support in DataSpell includes:
Editing and preview:
Ability to present a notebook as source code with textual cell definitions and manipulate cells as regular code.
Live preview of the cell execution output and Markdown content.
Auto-saving changes that you make in your files. Saving is triggered by various events, for example, closing a file or a project, or quitting the IDE.
Coding assistance:
Error and syntax highlighting.
Code completion.
Ability to create line commentsCtrl+/.
Ability to run cells and preview execution results.
Dedicated Jupyter Notebook Debugger.

Get familiar with the user interface
Mind the following user interface features when working with Jupyter notebooks in DataSpell.
Notebook editor
A Jupyter notebook opened in the editor has its specific UI elements:
Jupyter notebook toolbar: provides quick access to the most popular actions. The rest of the notebook specific actions are available in the menu.
Code cell: a notebook cell that contains an executable code
Cell output: results of the code cell execution; can be presented by a text output, table, or plot.
Cell toolbar: a toolbar of the code cell with the most popular commands. By default, cell toolbars are disabled. To enable them, open project settings/preferences (Ctrl+Alt+S), go to , and select the Show cell toolbar checkbox.
Cell toolbar
Each code cell has its configurable toolbar so that you can easily access the most popular commands and actions. By default, cell toolbars are disabled. To enable them, open project settings/preferences (Ctrl+Alt+S), go to , and select the Show cell toolbar checkbox.

Tool windows
The Server Log tab of the Jupyter tool window appears when you have any of the Jupyter server launched. The Server log tab of this window shows the current state of the Jupyter server and the link to the notebook in a browser.
It also provides controls to stop the running server (
) and launch the stopped server (
).
The Jupyter Variables tool window the detailed report about variable values of the executed cell.
