5 Must Know Facts For Your Next Test

1. Flask is known for its simplicity and ease of use, making it a great choice for building small to medium-sized web applications.
2. Flask is a microframework, which means it has a small and focused core with minimal dependencies, allowing developers to build applications with only the necessary components.
3. Flask is a WSGI (Web Server Gateway Interface) framework, which means it provides a standard interface for connecting web applications to web servers, allowing for flexibility in deployment.
4. Jinja2 is the default template engine used by Flask, which allows developers to create dynamic HTML templates and easily integrate them into their web applications.
5. Flask's minimalist design and flexibility make it a popular choice for building RESTful APIs, prototyping, and rapid development of web applications.
