However, his first love is Flask, with which he has built several products under the General Public License . Other than the Configuration class, most of this code should look familiar to you.
A good structure that contains complexity but can still be stringified is a Python dictionary. Therefore, I recommend that, whenever you want to send some data to the client, you choose a Python dict with whatever key-value pairs you need to convey information. To turn that dictionary into a properly formatted JSON response, headers and all, pass it as an argument to Flask’s jsonify function . In a given web application, you may want to be able to express relationships between objects. In the To-Do List example, users own multiple tasks, and each task is owned by only one user. This is an example of a “many-to-one” relationship, also known as a foreign key relationship, where the tasks are the “many” and the user owning those tasks is the “one.”
Advantages And Disadvantages Of Flask
While Python has various frameworks, such as Web2Py, TurboGears, and Django, developers prefer to use Flask for developing web applications. That’s all about some of the best courses to learn Flask and Python in 2022.

Flask is considered a “micro” framework because it’s lightweight and only provides essential components for web development such as request handling, routing, sessions, etc. But that doesn’t mean that Flask isn’t versatile; it supports extensions and custom-coded modules that add application features as if they were created within Flask. As we discussed earlier, Flask is a lightweight, simple and minimalist web framework, helping developers to build extensible and simple applications. Being a minimalist framework, it lacks some of the features such as data abstraction, bootstrapping, template engine, etc. Whereas Django is a full-stack Python web framework that includes several built-in features, such as URL routing, bootstrapping, migration and database abstraction.
Flask is a small and powerful web development framework for Python. It does not presume or force a developer to use a particular tool or library. Flask supports extensions that can add application features as if they were implemented in Flask itself. Flask’s main task is to build web applications quickly and with less code. With its lightweight and efficient web development framework, Flask combines rapid development and clean, simple design.

- I’ll describe those aspects of each framework in this series, which will begin with Flask.
- Like Flask, it’s easy to deploy by simply importing the library into any codebase and using it as a web server.
- Template files contain a set of static data and also allow incorporating further dynamic data.
- In the case of Linux OS, it ensures the OS level python is not disturbed by installing and using other python packages.
- Forms, another essential part of most web applications, come packaged with Django.
To also accept POST requests, which are sent by the browser when submitting forms, you’ll pass a tuple with the accepted types of requests to the methods argument of the @app.route() decorator. The purpose of this post is to give you a quick Python Flask tutorial on creating your first Flask application.
Flask Sample Project
The url_for() function will return the proper URL for each post based on its ID. In the next step, you’ll retrieve the posts you inserted into your database and display them in your application’s homepage. Once the file finishes execution, a new file called database.db will appear in your flask_blog directory. You’ve run your application and displayed information on the web browser. You’ve created the project folder, a virtual environment, and installed Flask. You’re now ready to move on to setting up your base application. Flask uses the Jinja template engine to dynamically build HTML pages using familiar Python concepts such as variables, loops, lists, and so on.
If it is a medium-sized app like forums, personal blogs, or small scale enterprise app, go for Flask. If you require a large scale app such as CMS or eCom website, Django can be your partner in crime. And Citrusbug’s expert Python developers have honed their skills in both the frameworks.
