Flask is a lightweight and flexible Python web framework that allows developers to build web applications with minimal setup and configuration.
It follows a microservices architecture, providing essential tools for building small to medium-sized applications while leaving room for customization through third-party extensions.
Learning Flask is important for aspiring web or backend developers because it offers simplicity, scalability, and great control over application structure, making it ideal for rapid development and API creation.
A tutor can accelerate the learning process by offering tailored lessons, hands-on coding exercises, and real-world project experience, helping learners quickly understand Flask's core concepts, integrate essential features, and build efficient, production-ready web applications with confidence.
