How does the use of a framework differ from using a third-party library in a project?

A framework sets the architectural principles and structure of an application; it "calls" your code and manages its execution (inversion of control). Using a framework means you write code within its rules and patterns.

An integrated third-party library is a set of ready-made functions or classes that you call as needed. You control when and how to use the library.

Example:

• Framework: Django in Python — it defines the project structure, routing, request handling.
• Library: requests — you call its functions for HTTP requests when needed.

Thus, the framework determines the architecture and lifecycle of the application, while the library provides auxiliary tools.
