Markdown cell in Jupyter notebook

Markdown cell in Jupyter notebook

In Jupyter Notebook (and Jupyter Lab), cells can be of different types, primarily: Code cells and Markdown cells. While Code cells contain code to be executed, Markdown cells contain text that is formatted using Markdown, a lightweight markup language.

Here's how you can work with Markdown cells in a Jupyter Notebook:

  1. Creating a Markdown Cell:

    • When you add a new cell (using the "+" button or the B shortcut key), it defaults to being a Code cell.
    • To change it to a Markdown cell, you can:
      • Use the cell type dropdown menu in the toolbar and select "Markdown".
      • Use the shortcut key M when the cell is in command mode (i.e., not actively being edited).

  2. Basic Markdown Syntax:

    • Headers: Use # for a level-1 header, ## for a level-2 header, and so on.

      # This is a Level-1 Header ## This is a Level-2 Header

    • Emphasis: Use * or _ to italicize and ** or __ to bold.

      *italic* or _italic_ **bold** or __bold__

    • Lists: Use * for bullet points and numbers for numbered lists.

      * Item 1 * Item 2 * Sub-item 1 1. First 2. Second

    • Links: Use this format: [Link Text](URL)

    • Images: Use this format: ![Alt Text](URL)

    • Code: Use backticks `. For inline code: `code`. For blocks of code, use triple backticks with optional language identifier:

      <pre> ```python def hello(): print("Hello, World!") ``` </pre>

    • Blockquotes: Use >:

      > This is a blockquote.

    • Horizontal Line: Use three dashes ---.

  3. Executing a Markdown Cell:

    • After you've entered your Markdown, you can render it by running the cell. This can be done by:
      • Clicking the "Run" button (play icon) in the toolbar.
      • Using the shortcut key Shift + Enter to run the cell and move to the next one or Ctrl + Enter to run the cell and stay in the same cell.

  4. Editing a Markdown Cell:

    • To edit the contents of a rendered Markdown cell, simply double-click on it. It'll revert to edit mode where you can make changes.

  5. Additional Features:

    • Jupyter's Markdown cells also support LaTeX for mathematical expressions. Wrap in-between $ for inline math and $$ for display math.
      • Inline: $y = mx + c$
      • Display: $$y = mx + c$$

Using Markdown cells effectively can make your Jupyter Notebook more readable and organized. They're excellent for providing context, explanations, or adding structure to your notebook.
