Datalore Help


A notebook in Datalore is a sequence of code and Markdown cells in a linear order. This means that when you work on a notebook, you create and edit its cells.

When you create a notebook and open it in the Datalore editor, it is one empty code cell. This is where you start your work on the notebook. As you complete this cell, you will add and edit the next one, and so on.

Cell interface and basic actions

Code cells and Markdown cells share two crucial interface elements that allow you to manage them:

  • Cell toolbar

  • Cell menu

Cell toolbar

Located in the upper-right corner of the cell frame, the toolbar contains the following icons:

  • Change cell visibility: allows to control which cell parts other users can see.

  • Insert code cell below: inserts a new code cell below the selected one.

  • Select cell language: allows to change the cell type and converts the input into the selected language.

  • 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. Since Markdown cells are executed automatically, they do not have this icon.

Cell menu

The cell menu is a popup menu accessed via the cell toolbar or by right-clicking anywhere in the editor field. This element contains an expanded selection of actions to manage the cells and their input. The exact set of actions depends on how you opened the cell menu.
