Dependency
Domain: Software Engineering
🎯 Motivation
External code your project relies on. Libraries, frameworks, packages. Must be managed carefully.
📋 Concrete Example
Dependencies: requests (HTTP), flask (web), pytest (testing). Your code imports and uses them. If requests has a bug, your code has a bug. If requests updates and breaks compatibility, your code breaks.
🔗 Analogy
Dependencies are like subcontractors on a construction site - you rely on the electrician, plumber, and painter. If the electrician does bad work, your building has electrical problems. Dependencies are your code’s subcontractors.
