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. At the end of the course, you will build a fully functional blog application using Flask. This is a complete hands-on course and ideal if you want to learn Flask in a few hours rather than days and weeks. After learning the basics, you will also learn about the Jinja template to create dynamic websites using Flask with minimal code.

And, if the request type is POST, we extract the `nm` parameter from the HTML Form and `redirect` the data to `success` URL. HTTP methods are at the core of communication between different parties of the world wide web, one of them being the Flask app you will be designing. These methods are standard across any frameworks, so let’s see how Flask handles them.

And because Flask was created to make building web applications very easy, you’ll find it not only useful but widespread. Instead of including the necessary abstraction layers for things like databases and form validation, Flask depends on extensions to add the necessary functionality. So think of Flask as an almost bare-bones framework that allows you to add functionality via extensions.

• Created by Jose Portilla, my favorite and one of the most popular Python instructors on Udemy, this is a great course to learn how o create fantastic websites using Flask in no time.
• In the United States, we use 8.5 x 11 paper instead of the A4 paper used in Europe and Asia, round bubble scantrons for tests, and three-ring binders.
• Upon refreshing the index page of your application, you will notice that the text Welcome to FlaskBlog is now in brown, centered, and enclosed inside a border.
• Werkzeug is one of the most advanced WSGI modules that contain various tools and utilities that facilitate web application development.

Since you want your view to handle one specific type of HTTP request, use app.route to add that restriction. The methods keyword argument will take a list of strings as a value, with each string a type of possible HTTP method. In practice, you can use app.route to restrict to one or more types of HTTP request or accept any by leaving the methods keyword argument alone.

For example, if a technology interfacing with your Flask app becomes obsolete or is discontinued, then the company will have to scramble to find a new compatible one. The more complicated the app becomes, the higher the potential maintenance and implementation costs. Developers love Python’s ease of use and efficiency, as it produces websites which are quick-loading and secure.

In the above example, we’ve 3 simple routes and their functions hard-coded in the traditional manner. Based on the input of the `country` variable, `url_for()` method redirects it to the appropriate function call. To understand Flask, we need to understand what is the traditional web framework.

Flask: Develop Web Applications in Python

You will flask framework for python developers lessons simple REST APIs with Flask, how to perform Authentication and Authorization with Flask, and also how to connect to a database like MySQL using Flask code. Talking about social proof, this course is created by Jose Salvatierra of Telcado, and it is one of the most popular Flask courses on Udemy. It has, on average, 4.6 ratings by 7753 participants, and more than 43K students have enrolled in this course. If you are a complete beginner at Python and Flask, you’ll find this course very useful.

In addition to solving the C10k issue , the asynchronous framework uses a non-blocking network I/O. The most desirable aspect of the Pyramid is the ability to work equally well with small as well as full-scale applications. Moreover, there is a multitude of resources available to extend its abilities as per the requirements call for.

Project Folder Structure

For those with a busy schedule who are unable to go to bootcamp in person, there are live online web development bootcamps with flexible scheduling options to fit within your busy life. There is much more that goes into an application than one view for creating new things. With Flask, a function is marked as a view when it is decorated by app.route. In turn, app.route adds to the application’s central configuration a map from the specified route to the function that runs when that route is accessed. The flask-sqlalchemy package leverages SQLAlchemy to set up and inform the database structure.
