Flask

Term from Software Development industry explained for recruiters

Flask is a lightweight and flexible system for building websites and web applications using Python programming language. Think of it as a simple toolkit that gives developers the basic tools they need while letting them choose additional features as needed. It's particularly popular for creating small to medium-sized web services and APIs (ways for different computer systems to talk to each other). Many companies use Flask because it's easy to learn, quick to set up, and doesn't force developers to follow strict rules like some other systems do. Similar systems include Django and FastAPI. These are called "web frameworks" and they help developers build web applications faster by providing ready-to-use components.
