Markdown In Python

Posted on  by admin

Introduction

Python-Markdown is a packagethat converts content in Markdown format to HTML. In this example, we will look at how to convert Markdown to HTML and automatically generate a table-of-contents.We will also look at using the command-line tool to convert content.We will also cover how to use fenced code blocks and

Setup

Install the markdown library with pip. I am using Python 3.8 in this example.

Convert Markdown to HTML in Python

Markdown is a lightweight Markup language with a plain text syntax. John Gruber developed the Markdown language in 2004 in a collaborative effort with Aaron Swartz, intending to enable people to.

The easiest way to convert is just use a string for input and a string for output.

The Python Markdown package is now maintained by Waylan Limberg. The new project website is here: Python Markdown at PyPy. Python-Markdown is a Python library that allows you to convert Markdown text to HTML; it mostly follows the Markdown standard, with a few minor differences to the standard Markdown syntax. In this tutorial, you’ll use Flask, SQLite, and Python-Markdown to build a small note-taking web application that supports formatting text using Markdown.

To use files for input and output instead:

Convert Markdown to HTML with command-line tool

The Python-Markdown CLI tool is convenient whenyou just want to convert a document without embedding the code in a larger application.

The easiest way to invoke it by running is a module with python -m. For example:

Linux Latex Markdown In this post, I am gonna show you how to write Mathematic symbols in markdown. Since I am writing blog post that hosted by Github with Editor Atom, and use plugin markdown-preview-plus and mathjax-wrapper, and use mathjax Javascript display the math symbols on the web page. While Python-Markdown strives to fully implement markdown as described in the syntax rules, the rules can be interpreted in different ways and different implementations occasionally vary in their behavior (see the Babelmark FAQ for some examples). Known and intentional differences found in Python-Markdown are summarized below.

Generate a table of contents (TOC)

To generate a TOC, we need to using the toc extension. There are a number of other extensions availablewith the package that you can check out at https://python-markdown.github.io/extensions/.

You convert the same way before, except this time you pass in an extra parameter to include the extension

To customize options, you need to include the markdown.extensions.toc.TocExtension classand pass an instance of that object to the extensions parameter. See the following example.Read more at https://python-markdown.github.io/extensions/toc/#usage

In your Markdown, add [TOC] to the Markdown where the TOC should go.

Fenced code blocks

To make a code block you can indent all lines by 4 spaces by default.Personally, I prefer using the three backticks (```) to enclose code without indenting.It also gives a place to define which language is being used.

See Full List On Math.ubc.ca

To use the triple backticks you need to enable the fenced_code extension.This extensions already comes with Python-Markdown.This will wrap the code block with a <pre> and <code> tag.

TIP: If you need to write a triple backtick code block within your Markdown code, you can wrap the outermostcodeblock with additional backticks. For example, use a set of 4 or 5 instead of 3 like this:

Source code syntax highlighting

To build on the previous section using fenced_code, you can add syntax highlightingwith the codehilite extension. This extensions already comes with Python-Markdown, butit depends on another Python library named Pygments.

Install pygments with pip:

Here is an example of generating HTML with both fenced_code and codehilite extensions together.

When you add the codehilite extension,the code block is wrapped with the class .codehilite and many other styles will be applied.You could write your own styles, but Pygments comes with several style sets you can use.You can generate the different styles using a command-line tool called pygmentize.Use this tool to list available color themes and to generate the styles.Save the CSS output to a .css file and link it in your HTML like normal.

To apply the proper styles, you must generate the CSS and apply it.

In the HTML:

Conclusion

After reading this, you should understand how to convert Markdown contentto HTML and how to automatically generate a table-of-contents.You should be able to use strings or files for conversion.You should also understand how to use the CLI tool to convert content.You should also know how to include extensions and apply fenced code blocks and source code syntax highlithing with Pygments.

Lists

Create an ordered list using numbers:

  1. Number theory
  2. Algebra
  3. Partial differential equations
  4. Probability
Markdown In Python

Create an unordered list using an asterisk * for each item:

  • Number theory
  • Algebra
  • Partial differential equations
  • Probability

Use indentation to create nested lists:

  1. Mathematics
    • Calculus
    • Linear Algebra
    • Probability
  2. Physics
    • Classical Mechanics
    • Relativity
    • Thermodynamics
  3. Biology
    • Diffusion and Osmosis
    • Homeostasis
    • Immunology

Links

Create a link with the syntax [description](url). For example:

creates the link UBC Math.

Images

Include an image using the syntax ![description](url). For example:

displays the image

Tables

Markdown In Python

Create a table by separating entries by pipe characters :

Python OperatorDescription
+addition
-subtraction
*multiplication
/division
**power

The syntax :---: specifies the alignment (centered in this case) of the columns. See more about GitHub flavoured markdown.

Exercises

  1. Create a numbered list of the top 5 websites you visit most often and include a link for each site.
  2. Write a short biography of your favourite mathematician, provide a link to their Wikipedia page and include an image (with a link and description of the source).
  3. Create a table of all the courses that you have taken in university. Include the columns: course number, course title, year (that you took the class), and instructor name.
