Markdown in Jupyter Notebook
Markdown is a lightweight and versatile markup language commonly used for formatting text in documents, web pages, and, in the context of Jupyter Notebook, for creating well-structured and visually appealing content within your notebooks. In this section, we’ll explore the basics of Markdown in Jupyter Notebook, which is a powerful tool for documenting and explaining your code and analysis.
What is Markdown?
Markdown is a plain-text formatting syntax that allows you to add structure and style to your documents without the complexity of traditional markup languages like HTML. With Markdown, you can easily create headings, lists, links, images, equations, and more using simple and intuitive syntax.
Markdown Cells in Jupyter Notebook
Jupyter Notebook provides Markdown cells alongside code cells, allowing you to intersperse formatted text, explanations, and documentation with your code. Markdown cells are a valuable tool for communicating your thought process, documenting your analysis, and making your notebooks more understandable for others.
Markdown Basics
Let’s explore some fundamental Markdown elements you can use in Jupyter Notebook:
Headings
Markdown uses hashtags (#
) to define headings. The number of hashtags determines the heading level:
# Heading 1
## Heading 2
### Heading 3
#### Heading 4
Text Formatting
You can emphasize text using asterisks (*
) or underscores (_
):
*italic* or _italic_
**bold** or __bold__
Lists
Markdown supports both ordered and unordered lists:
Unordered List:
- Item 1
- Item 2
- Subitem 2.1
- Subitem 2.2
- Item 3
Ordered List:
1. First item
2. Second item
3. Third item
Links
You can create links using square brackets for the link text and parentheses for the URL:
[OpenAI's Website](https://www.openai.com/)
Images
Inserting images is similar to creating links, but with an exclamation mark (!
) in front:
![Alt text](image_url)
Code Blocks
You can include inline code using backticks (`
) and code blocks using triple backticks (```
):
Inline Code: print("Hello, World!")
Code Block:
def greet():
print("Hello, World!")
Horizontal Lines
Create horizontal lines with three or more asterisks (***
), hyphens (---
), or underscores (___
):
***
Blockquotes
Use the greater-than sign (>
) for blockquotes:
> This is a blockquote.
Tables
Markdown supports simple tables using pipes (|
) and hyphens (-
) for headers:
| Header 1 | Header 2 |
|----------|----------|
| Cell 1 | Cell 2 |
| Cell 3 | Cell 4 |
Equations
You can write mathematical equations in Markdown using LaTeX syntax. To create an inline equation, wrap the LaTeX code in single dollar signs ($
), like this: $E=mc^2$
. To create a centered equation on its line, use double dollar signs ($$
) on separate lines:
$$
E=mc^2
$$
These are just a few of the essential Markdown elements you can use. Markdown is highly customizable, and you can explore more formatting options and extensions to suit your specific needs.
Markdown and Jupyter Notebook
In Jupyter Notebook, you can create Markdown cells by selecting “Markdown” from the cell type dropdown in the toolbar or by using the keyboard shortcut M
while in command mode. Once in a Markdown cell, you can start typing your Markdown content.
To render the Markdown cell and see the formatted output, press Shift + Enter
.
Markdown in Jupyter Notebook is a valuable tool for creating well-documented and visually appealing notebooks. It allows you to combine code, explanations, visualizations, and mathematical equations seamlessly, making your work more understandable and shareable.
In the next sections, we’ll explore more advanced Markdown techniques, including tables, HTML integration, and additional LaTeX equation options, to help you take your Jupyter Notebook documentation to the next level.
