The most obvious and user-friendly URL route for the about page is “/about” (referring to line #10 in the solution). As discussed before, the WSGI aspect of the application is taken care of by the Flask module. This prefix is an indication that the environment env is currently active, which might have another name depending on how you named it during creation. If you are looking for information on a specific function, class or
method, this part of the documentation is for you. Flask depends on the Werkzeug WSGI toolkit, the Jinja template engine, and the
Click CLI toolkit. Be sure to check their documentation as well as Flask’s when
looking for information.
If you’re using PyCharm, you can benefit from its support for custom template tags. That’s all about some of the best courses to learn Flask and Python in 2024. As I said, Flask is a great Python framework for web development.
Jinja2 – A templating language
You will create 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. Within flaskapp/, create a folder, app/, to contain all your files. Inside app/, create a folder static/; this is where we’ll put our web app’s images, CSS, and JavaScript flask developer files, so create folders for each of those, as demonstrated above. Additionally, create another folder, templates/, to store the app’s web templates. Create an empty Python file routes.py for the application logic, such as URL routing. And no project is complete without a helpful description, so create a README.md file as well.
- There’s hardly any difference for basic applications, but you may face some limitations if you need to perform advanced operations in your templates.
- The HTML files (‘home.html’ and ‘about.html’) should be placed in a ‘templates’ folder in the same directory as your Flask application.
- Both Django and Flask are equally suitable for many different tasks, but there are also so many aspects in which they differ.
- Next you import the flask package with import flask; then print the Flask version, which is provided via the flask.__version__ variable.
You add the page’s title inside the header block and wrap it within title. Jinja will understand this structure and render the page’s title in the header and title blocks. After importing Blueprint, you create an instance of it named bp. The first argument, “pages”, is the name of your blueprint. You’ll use this name to identify this particular blueprint in your Flask project. You’ll use this later when you import pages into __init__.py.
Make Your Project Look Nice
Get started with Installation
and then get an overview with the Quickstart. There is also a
more detailed Tutorial that shows how to create a small but
complete application with Flask. Common patterns are described in the
Patterns for Flask section. The rest of the docs describe each
component of Flask in detail, with a full reference in the API
section. We’ve also discussed how Flask handles HTTP requests and responses, adheres to the WSGI standard, and can be structured based on the MVC pattern.
- If you’re a web developer using Python as your server-side programming language of choice, you have a number of Python libraries and web frameworks to choose from.
- Data is stored in databases, which are provided by different vendors.
- The simplest Flask application can be made using only one script!
- Once you have got a hold of Python, you start exploring Flask for building professional REST APIs with Python.
Let’s learn what these terms mean, and their significance concerning Flask. Stop the development server in your other terminal that runs the hello application with CTRL+C. You’ve run your application and https://remotemode.net/ displayed information on the web browser. The hello() view function returns the string ‘Hello, World! The templates in your project provide the logic and structure for the front end of your project.
