This is a medium-difficulty Python language-knowledge question that assesses whether you understand the modern Python packaging ecosystem. While it may seem like a straightforward definitions question, it probes practical familiarity with how Python distributions are built, versioned, and deployed—knowledge that matters in production environments and quantitative finance codebases alike.
To answer confidently, you need to distinguish wheel files from related concepts in Python packaging, such as source distributions, eggs, and plain module directories. The question rewards understanding not just the name, but the structural properties that make wheels the standard installation format: their platform-specificity, their role in dependency resolution, and how they differ from older or alternative packaging approaches.
