Python - Flask

Flask is a lightweight and flexible web framework written in Python that is used to build web applications. Flask is classified as a “microframework” because it provides the essential tools to create web applications, but does not impose a specific structure or components, giving developers great flexibility and freedom to choose the libraries and tools to use in different projects.

Some features of Flask are:

Routing: Flask allows defining how to respond to different URLs.

Templates: facilitates the dynamic generation of web pages using templates.

Database integration: allows connecting your Flask application to various databases.

Extensions: offers a variety of extensions that add additional functionality, such as authentication, session management and more.

Rapid development: Flask focuses on simplicity and is ideal for agile and fast web application development.

Flask is widely used in the Python development community due to its ease of learning and its ability to adapt to a wide range of web projects. It is an excellent choice for those who want to create web applications with Python without being overwhelmed by the complexity of more comprehensive frameworks.
