Jupyter kernelspec list Use a markdown kernel by itself. Markdown-kernel is a simple Jupyter kernel that displays cell content as markdown. To use this kernel, you can start a Jupyter server with command jupyter notebook or jupyter lab, create a notebook with this kernel, enter and render markdown texts. In Jupyter Notebooks, Markdown Cells are the easiest way to write and format text. For a more thorough explanation of how to write in Markdown cells, refer to this section of the guide. 2.3 Raw Cells ¶.

).You can use either the Menu tools or Keyboard Shortcuts to create new cells.
Function | Keyboard Shortcut | Menu Tools |
---|---|---|
Create new cell | Esc + a (above), Esc + b (below) | Insert→ Insert Cell Above OR Insert → Insert Cell Below |
Copy Cell | c | Copy Key |
Paste Cell | v | Paste Key |
While the default cell type for new cells is Code, you can change the cell type of any existing cell by clicking in the cell and selecting a new cell type (e.g. Markdown
) in the cell type menu in the toolbar.
Cell type options include Code, Markdown, Raw NBConvert (for text to remain unmodified by nbconvert), and Heading.
To use the Keyboard Shortcuts, hit the esc
key. After that, you can change a cell to Markdown by hitting the m
key, or you can change a cell to Code by hitting the y
key.
You can run any cell in Jupyter Notebook
(regardless of whether it contains Code or Markdown
) using the Menu tools or Keyboard Shortcuts.
Function | Keyboard Shortcut | Menu Tools |
---|---|---|
Run Cell | Ctrl + enter | Cell → Run Cell |
For example, you can add a new Code cell and then run the following Python
code (e.g. 3 + 4
). Your result, or output, will be displayed below the Code cell that you run. The wind and wilting blossom for mac.
You can run Markdown
cells in the same way that you can run code cells. However, when you run a Markdown
cell, the text formatted using Markdown
syntax will be rendered as stylized text.
This means that headings are larger and bold, bulleted lists have bullets next to them instead of *
, and regular text looks normal. No outputs will appear below the Markdown cell.
For example, the Markdown
syntax below represents 3 headers. You can double-click in any Markdown
cell to see the raw Markdown
syntax, which for the cell below would appear like this raw Markdown
syntax:
To see the Markdown
as stylized text, run the cell. It should look like the text printed below:
You can change the order of cells within Jupyter Notebook
using the up arrow
and down arrow
buttons on the menu bar. To do this, click inside the cell that you want to move and then press the desired arrow as many times as you need to move the Cell to the desired location.
Sometimes, you may want to clear any output results that have been produced. You can do this using the Menu:
Menu Tools |
---|
Cell -> Current Outputs -> Clear |
This will clear the current cell that you are working in, which you can activate by clicking in a cell.
You can also clear all of the output using the Menu Tools.
