QR Code Generator (Python)

A minimal command-line tool that converts any URL into a QR code image. The script uses the qrcode Python library to generate the QR and saves it as a PNG file with a user-specified filename.

How It Works

1. Prompts the user for:

   • A URL
   • The file name to save the QR code

2. Ensures the filename ends with .png:

   if not(filename.endswith(".png")):
       filename += ".png"

3. Generates the QR using:

   img = qrcode.make(url)

4. Saves the image to disk:

   img.save(filename)
