To start a Flask project with Poetry, first, make sure you have Poetry installed. If not, visit the official Poetry website for installation instructions. You use the python command line interface with the option -c to execute Python code. Next you import the flask package with import flask; then print the Flask version, which is provided via the flask.__version__ variable. In this step, you’ll activate your Python environment and install Flask using the pip package installer. Philipp is a Berlin-based software engineer with a graphic design background and a passion for full-stack web development.

First, we’ll briefly go over the main ways in which web developers use Python in digital systems, then we’ll introduce the Flask microframework itself. Web templates are simply text files that contain variables and control flow statements (if..else, for, etc), and end with an .html or .xml extension. Enter your newly created development environment and activate it so you can begin working within it. Virtualenv is a useful tool that creates isolated Python development environments where you can do all your development work. Because systems vary, things can sporadically go wrong during these steps. If they do, just Google the error message or leave a comment describing the problem.

This is a project-based course, which means you will be working on a static application and building it from scratch. After learning the basics, you will also learn about the Jinja template to create dynamic websites using Flask with minimal code. In this course, you will first learn the basics of Flask to get you started with Python web development. The course will first teach you how to create view functions and generate simple HTML pages.

While FastAPI is a relatively new player in the Python API framework space, it has been rapidly gaining momentum and attracting a growing community of developers. Flask’s micro framework architecture makes it an excellent fit for small to medium-sized projects where simplicity, speed, and efficiency are paramount. It strikes a balance between providing essential features and keeping complexity at bay, ensuring that your project remains manageable and agile. The modular nature of Flask grants developers unparalleled flexibility. You have the liberty to choose and integrate only the components you require, preventing unnecessary complexity. This customization not only streamlines development but also results in leaner applications that are easier to maintain, upgrade, and scale.

Knowledge and experience of rolling out projects using both Django and Flask can seriously add value to your skillset (and potentially boost your full-stack developer salary, too). Flask developers will unfortunately have to write all of their own SQL statements by themselves, which can add a lot of extra work. Not only is this helpful in terms of allowing your project to move in another direction easily, it also makes sure that the structure won’t collapse when a part is altered.
