How to convert string to seo-url?

@stephon 

To convert a string to an SEO-friendly URL, follow these steps:

1. Remove all non-alphanumeric characters from the string: This includes spaces, punctuation marks, special characters, and symbols. Use regex or string methods to replace these characters with an empty string or a specific delimiter.
2. Replace spaces with hyphens or underscores: Spaces are not allowed in URLs, so replace them with hyphens ("-") or underscores ("_") to make the URL readable.
3. Convert the string to lowercase: SEO URLs are case-insensitive, and lowercase URLs are more readable and user-friendly.
4. Remove duplicate or unnecessary hyphens/underscores: If there are multiple consecutive hyphens or underscores, replace them with a single hyphen or underscore to maintain readability.
5. Trim any leading or trailing hyphens/underscores: Remove any hyphens or underscores at the beginning or end of the URL to make it cleaner.
6. Shorten the URL if necessary: Consider abbreviating long words or removing unnecessary words to create a concise and descriptive URL while still maintaining readability.

import re

def string_to_seo_url(string):
    # Step 1 - Remove non-alphanumeric characters
    string = re.sub(r'W+', '', string)

    # Step 2 - Replace spaces with hyphens
    string = string.replace(' ', '-')

    # Step 3 - Convert to lowercase
    string = string.lower()

    # Step 4 - Remove duplicate hyphens
    string = re.sub(r'[-]+', '-', string)

    # Step 5 - Trim leading/trailing hyphens
    string = string.strip('-')

    # Step 6 - Shorten the URL if necessary

    return string

This implementation is a basic guideline, but you may need to customize it according to your specific requirements or any additional rules that need to be followed for SEO URLs.
