[jayasahan]

What does this PR do?

I have made a template of a URL shorter with Python using Appwrite functions

Test Plan

After this, I would make a basic URL shortener and add it to this.

Have you read the Contributing Guidelines on issues?

Yes

This is the example URL shortener

from appwrite import Client

client = Client(
    "YOUR_API_ENDPOINT",
    "YOUR_API_KEY"
)

long_url = "https://example.com"
short_url = shorten_url(long_url)

print("Shortened URL:", short_url)

And my instrutions

To run this script, you will need to replace YOUR_API_ENDPOINT and YOUR_API_KEY with your own Appwrite project settings. You can then run the script from the command line:

python shorten_url.py

This will print the shortened URL to the console. You can then use this short URL to access the original long URL.
