In this tutorial, you’ll build a small web application that demonstrates how to handle common errors one encounters when developing a web application. You’ll create custom error pages, use the Flask debugger to troubleshoot exceptions, and use logging to track events in your application. In Flask, you can use the Jinja templating language to render HTML templates.

You get to decide how you want to implement things, in other words. At its core, Flask is simple yet extensible, which is perfect for developing RESTful APIs and microservices. Through Flask programming, users can generate amazing products effectively, as it provides simplicity, flexibility and fine-grained control. The core of Flask programming is easy to understand and use, and it also allows the integration of multiple extension as well, which can amplify the features of Flask. Being developed in Python makes it even better as it is one of the most used languages on the planet hence making it better than many other frameworks available. Flask provides configuration and conventions, with sensible defaults, to get started.

Take your REST APIs to a whole new level with this advanced Flask and Python course!

You won’t have to sit there second guessing yourself while researching everything on your own. Deploy your own Flask application so you can share your app with the world. By the end of this course, you will be able to write code for a Flask web application.

The following tutorials will guide you through more advanced topics and provide solid learning materials, especially when combined with the example real-world projects listed in the next section. The „Hello, World!” code for Flask Whats the best Microsoft Azure certification path? is just seven lines of code but learning how to build full-featured web applications with any framework takes a lot of work. These resources listed below are the best up-to-date tutorials and references for getting started.

Is Flask a frontend or backend?

Thanks to Flask, a backend this compact and controlled is capable of handling all the data processing required to support a full-featured frontend finance tracking app for fiscal fanatics, like me! I hope you've enjoyed my article on Flask as a compact backend development tool for Python.

I can help you with Python and JavaScript issues, particularly in web and backend development. I’m experienced with programming libraries and frameworks like Flask, React, React Native, and AngularJS. I’ve worked extensively with UNIX systems, MongoDB, PostgreSQL, and advanced system architecture design. At this point, a user should have already logged, making it possible for example to present him with menu items only available to registered users. Upload files that contain software or other material protected by intellectual property laws unless you own or control the rights thereto or have received all necessary consents.

API Reference¶

You use a database to store and maintain persistent data that can be retrieved and manipulated efficiently. PostgreSQL, or Postgres, is a relational database management system that provides an implementation of the SQL querying language. In this tutorial, you’ll build a small book review web application that demonstrates how to use the psycopg2 library, a PostgreSQL database adapter. Top 100+ Linux Interview Questions and Answers 2022 SQLite is a simple and fast open source SQL engine that can be used with Python to store and manipulate application data. SQLite works well with Python because the Python standard library provides the sqlite3 module, which you can use to interact with any SQLite database. In this tutorial, you’ll build a small web application that demonstrates how to use SQLite with Flask.

In web applications, you usually need a database, which is an organized collection of data. SQLAlchemy is an SQL toolkit that provides efficient and high-performing database access for relational databases.


Flask is a lightweight Python web framework that provides useful tools and features for creating web applications in the Python Language. It gives developers flexibility and is an accessible framework for new developers because you can build a web application quickly using only a single Python file. Flask is also extensible and doesn’t force a particular directory structure or require complicated boilerplate code before getting started. Learning Flask will allow you to quickly create web applications in Python. You can take advantage of Python libraries to add advanced features to your web application, like storing your data in a database, or validating web forms.

Practice in JavaScript, Java, Python, R, Android, Swift, Objective-C, React, Node Js, Ember, C++, SQL & more. You’re getting well tested code that’s been running in production. Tons of edge cases have been ironed out, and features were added due to real life needs. You’re going to see how the application gets built up from a single file, all the way to a 4,000+ line project that spans across dozens of files and folders. Create your own Flask application and add functionality with templates and forms. This course will help you get started with Python web development. Flask is a Python web framework used for building web applications.

Deep Dive into Flask’s Application and Request Contexts

In this tutorial, you’ll build a small web application that demonstrates how to render and validate web forms using Flask-WTF. When you’re developing a web application, you will inevitably run into situations where your application behaves in a way contrary to what you expected.
