Web application development with Python Flask

Flask is one of the most popular web frameworks in Python. It is a light-weight micro-framework that makes it very easy to start writing web applications, but it is also feature rich so you can create complex applications. In this course we'll start from a basic application just to display Hello World. Then we are going to learn how to create user interaction with the back-end. We'll learn how to use both SQL and NoSQL as the back-end database of the application. By the end of the course you'll be able to create the back-end of impressive web applications.
