Edit code
Use the main building element of your notebooks, code cells, to write and edit executable code. The default language that you use in code cells is Python. However, you can choose Kotlin when creating a notebook.
First code cell
By default, the empty code cell is where you start coding in your new notebook. Your cursor is already placed inside this cell.
Write your code.
Click the Run icon in the upper left corner of the cell to have the code executed. The result of the computation (output) will be displayed in the same cell right under the input.
You can use more run options. For more information, see Run code.
Add a code cell below the selected one
Click the Add code cell button.
Click the + icon on the selected cell toolbar.
Press Ctrl+Alt+Enter.
Add a code cell above the selected one
Press Ctrl+Shift+Enter.
Right-click anywhere in the editor field and select Insert code cell above from the menu.
Move cells
Now that you have more than one cell in your notebook, you can reorder them:
Press Ctrl+Shift+↑ or Ctrl+Shift+↓ to move the selected cell one cell up or one cell down.
Right-click the cell and try the same actions from the cell menu.
Code cell toolbar
Located in the upper right corner of the cell frame, the toolbar contains the following icons:
Select cell type: converts the code cell type into a Markdown or SQL cell (input converted accordingly).
Ask AI: opens the Ask AI tool that generates code suggestions for this code cell based on your prompts.
Insert code cell below: inserts a new code cell below the selected one.
Delete cell: deletes the cell from the notebook.
More actions: provides more options to insert, run, and move cells, or extract code to file.
Additionally, code cells have the Run icon. Located in the upper left corner, it executes the cell input and displays the output.
Code cell menu
The code cell menu is a popup menu opened by right-clicking anywhere in the code cell. This element contains an expanded selection of actions to manage the cell and its input.
Action | Details |
|---|---|
Insert code cell above/below | Inserts a new code cell below or above the selected one. |
Insert cell above/below | Inserts a cell of a selected type below or above the selected one. |
Delete cell | Deletes the selected cell. |
Change cell type | Changes the type of the selected cell and converts the input. |
Split cell at cursor | Splits the cell in two where the cursor is positioned. |
Copy link to cell | Copies the link to the cell to the clipboard. |
Clear output | Clears the cell output. |

Move cell up/down | Moves the selected cell one cell up or one cell down. |
Code cell output and view
You can have different kinds of code cell output, including text, tables, graphics, and so on. By default, the layout of a code cell displays both its code and output placed vertically.
To change how your cells are displayed, go to and try different options. For more information, see Customize the editor.
Collapse inputs and outputs
When working with big notebooks, you may want to collapse some or all of its inputs or outputs. You have the following options:
Collapse all inputs or outputs: go to and select the required action.
Collapse the input or output of a specific cell: click one of the two minus controls on the left side of the cell. To expand it, click the plus control.
