  • The success of any technology depends on the community that has been created around it.

When developing a web application, you will frequently run into situations where the application displays an error instead of the behavior you expect. You may misspell a variable or forget to define or import a function. To make fixing these problems easier, Flask provides a debugger when running the application in development mode. In this step, you will learn how to fix errors in your application using the Flask debugger. You now have a simple Flask application in a Python file called app.py, in the next step, you will run the application to see the result of the hello() view function rendered in a web browser. Once you create the app instance, you can use it to handle incoming web requests and send responses to the user.

MIT’s Introduction to Computer Science Using Python is a popular self-paced online class designed to give newcomers a comprehensive overview of Python programming. It will take you from “hello world” to understanding topics such as Python syntax, data structures, data types, basic algorithms, and debugging Python code. My goal is to make a second course, which would introduce more advanced back end concepts and then start the front end courses soon after that. Flask is an API of Python that allows us to build up web-applications.

One of the greatest advantages of Flask is that it’s simpler than Django. While both are well documented, Flask is just easier for developers to get their heads around. We briefly considered switching to Django then, but decided against it once we realized that that would be even more expensive.
