How to Create a Simple Markdown to HTML Converter in Python

Markdown is a popular format for writing content that’s easy to read and write, but converting it to HTML can be a hassle. In this post, I’ll show you how to create a simple Markdown to HTML converter using Python. This tool will allow you to convert your Markdown files into beautifully formatted HTML documents with just a few commands.

What You’ll Need

• Python: Make sure Python is installed on your system.

• Markdown Library: We’ll use the markdown library to handle the conversion.

Step-by-Step Guide

1. Set Up Your Project

Create a new directory for your project and navigate into it:

mkdir markdown_to_html
cd markdown_to_html

1. Install the Markdown Library

Install the markdown library using pip:

pip install markdown

1. Create Your Python Script

Create a new file named md_to_html.py:

touch md_to_html.py

Open md_to_html.py and add the following code:

import markdown
import sys

def markdown_to_html(md_text):
    """Convert Markdown text to HTML."""
    return markdown.markdown(md_text)

def main():
    if len(sys.argv) != 3:
        print("Usage: python md_to_html.py input.md output.html")
        sys.exit(1)

    input_file = sys.argv[1]
    output_file = sys.argv[2]

    try:
        with open(input_file, 'r') as f:
            md_text = f.read()
    except FileNotFoundError:
        print(f"Error: The file '{input_file}' does not exist.")
        sys.exit(1)

    html_text = markdown_to_html(md_text)

    with open(output_file, 'w') as f:
        f.write(html_text)

    print(f"Converted '{input_file}' to '{output_file}'")

if __name__ == "__main__":
    main()

1. Run Your Converter

Save your script and run it from the terminal:

python md_to_html.py example.md example.html

With just a few lines of Python code, you’ve created a powerful tool to convert Markdown to HTML. This simple script can be customized and extended to fit more advanced needs, but it’s a solid start for anyone looking to streamline their Markdown-to-HTML workflow.
