Phantom Dependencies: Is Your Requirements.txt Haunted?

This 26-minute PyCon US talk explores the hidden components within Python packages that aren't visible in your requirements.txt file. Discover how Software Bill-of-Materials (SBOMs) can help manage the complex dependency graphs in modern software systems that often combine Python with C, C++, Rust, and JavaScript. Learn how SBOMs enable better static code analysis, license compliance, vulnerability management, and regulatory compliance. By the end of the presentation, gain a clear understanding of what Software Bill-of-Materials documents are, their practical benefits, and how to respond when someone requests one from your project.
