python-qrcode is a Python library that generates QR code images.
The tool solves the problem of encoding data into QR codes by providing a pure Python implementation that requires no external compiled dependencies. It works by accepting data through a simple API, applying error correction, and rendering the result to various image formats. Users can generate codes with a single function call for basic use cases or configure detailed parameters like error correction level, box size, border width, and colors through the QRCode class for advanced control.
The library suits projects that need QR code generation without heavy dependencies. A standard installation uses pypng for PNG output and can render codes to the console, while installing with the pil extra enables Pillow for additional image functionality. Beyond raster formats, the tool supports SVG output through multiple factories: a path-based factory, a rectangle-based factory, and a fragment factory for embedding. Choose this tool if you need straightforward QR generation in Python with flexibility in output format and minimal setup overhead.
The project maintains steady activity with regular commits addressing bug fixes and feature requests. Development includes responsiveness to user-reported issues and incorporation of community contributions. The codebase shows consistent attention to both the core generation logic and the extensible image factory system that allows new output formats to be added.
