ReportLab Toolkit

The ReportLab Toolkit is an open-source Python library for generating high-quality PDF documents and graphics. It provides both low-level APIs for precise control over PDF elements and a higher-level framework (PLATYPUS) for creating complex, structured documents with flowables like paragraphs and tables. Currently at version 4.4.10, ReportLab is actively maintained with regular updates and is widely used for dynamic, data-driven report generation, including by Wikipedia for its 'Download as PDF' feature.
