As a follow up to my Setting Up a Flask Application in PyCharm article, today I'm going to show you how to set up your project with Visual Studio Code (Code, for short), which is a free and open source integrated development environment from Microsoft with great support for Python. Like I did in the previous article, you can see me going through all the required steps to set up an example project in the video below. After the video, I provide a short written summary of the process.

In this chapter I'm going to show you how to work with a temperature and humidity sensor.

One of the signatures of the Flask framework is its clever use of decorators for common application tasks such as defining routes and error handlers. Decorators give a very concise and readable structure to your code, so much that most Flask extensions and many other Python packages follow the same pattern and expose core parts of their functionality through decorators.

Today I'm starting a series of in-depth posts about different ways in which you can incorporate custom decorators into your Python applications. In this first part I'm going to show you how to create simple decorators that register functions as callbacks for application-specific events.

In this chapter you are going to learn how to install and use MicroPython on your ESP8266 microcontroller board.

Welcome to my MicroPython and the Internet of Things tutorial!

In this first part I want to give you a brief overview of what this tutorial is about, and more importantly, provide you the list of components that you are going to need.

I'm happy to announce a new multi-part tutorial that I will soon begin publishing on this blog and several other platforms. The tutorial is titled MicroPython and the Internet of Things and is a beginner tutorial that will introduce you to the exciting world of microcontrollers and small-form Internet enabled devices.

When you deploy your application on a server, you need to make sure the application runs uninterrupted. If the application crashes, you'd want it to automatically restart, and if the server experiences a power outage, you'd want the application to start immediately once power is restored. Basically what you need is something that keeps an eye on the application and restarts it if it ever finds that it isn't running anymore.

In previous tutorials, I showed you how to implement this using supervisord, which is a third party utility written in Python. Today I'm going to show you a similar solution based on systemd, which is a native component in many Linux distributions including Debian derivatives such as Ubuntu and RedHat derivatives such as Fedora and CentOS.

One of the most rewarding aspects of having a popular course online is that from time to time I get a question that forces me to learn something new. The other day a reader asked me how they can write a database query with an unusual ordering, and I had to stop for a minute (okay, it was more like half an hour) to think about how to do it within the context of a Flask and Flask-SQLAlchemy application. Are you ready to see some advanced SQLAlchemy action?
