Python QR Generator

Small command-line helper that turns a URL (or any text) into an image-based QR code using the qrcode Python library.

Prerequisites

• Python 3.8 or newer
• pip for installing dependencies

Installation

python -m venv .venv
.venv\Scripts\activate  # On macOS/Linux use: source .venv/bin/activate
pip install qrcode[pil]

Usage

python generator.py

You'll be prompted for:

• URL: Any text or link that should be encoded
• filename: The output image name (saved as <filename>.jpg)

Example:

Enter your URL: https://example.com
Enter the filename: example-qr
QR-Code generated!

The QR image is saved alongside the script, e.g. example-qr.jpg.

Customizing

• Adjust the QR appearance (size, colors, error correction) by tweaking the arguments passed to qrcode.QRCode in generator.py.
• Replace .jpg with .png in the final generate call if you prefer PNG output.

Troubleshooting

• ModuleNotFoundError: No module named 'qrcode'
  Ensure the virtual environment is activated and rerun pip install qrcode[pil].
