A software framework is a pre-built collection of tools, libraries, and best practices that developers use to create applications more efficiently. It provides a structured foundation, allowing programmers to focus on the unique aspects of their projects rather than starting from scratch. Common examples of software frameworks include Django for web development and TensorFlow for machine learning. Frameworks often include reusable code components, which help streamline the development process and ensure consistency across applications. They also promote good coding practices and can simplify tasks like database management, user authentication, and API integration, making it easier for developers to build robust software solutions.
