Full Stack Web Development with Flask
This comprehensive course will teach you how to build dynamic web apps using Python and Flask. You’ll set up your environment, create a Flask project, and work with templates and databases. By the end, you’ll have the skills to build your own personal or professional web application. Now that you have your programming environment set up, you’ll start using Flask. In this step, you’ll make a small Flask web application inside a Python file, in which you’ll write HTML code to display on the browser. In the next section, you get to learn the basics of Tkinter which will allow you to build desktop Python applications having an attractive user interface.
- And here’s the GitHub repository codebase you will use as part of this tutorial.
- We guarantee that all our online courses will meet or exceed your expectations.
- You will save your code to GitHub, design, and style the Application using Flask Bootstrap, use SQLAlchemy ORM to query data and finally deploy it to the web-hosting platform Heroku.
- In addition to the default string variable part, other data types like int, float, and path(for directory separator channel which can take slash) are also used.
- You then use it to create your Flask application instance with the name app.
- In this step, you’ll activate your Python environment and install Flask using the pip package installer.
You pass the special variable __name__, which holds the name of the current Python module. This name tells the instance where it’s located; you need this because Flask sets up some paths Advanced Python Web Dev Using Flask Lessons behind the scenes. In the preceding code block, you first import the Flask object from the flask package. You then use it to create your Flask application instance with the name app.

Using Flask and popular extensions Flask-RESTful, Flask-JWT, and Flask-SQLAlchemy we will dive right into developing complete, solid, production-ready REST APIs. We will also look into essential technologies Git, Heroku, nginx, and Varnish. Through hands-on, practical experience, you will go through concepts like creating a Flask Application, using Templates in Flask Applications, using SQLAlchemy and SQLite with Flask, and using Flask and WTForms. Message is actual text to be displayed and category is optional which is to render any error or info.
Once you create the app instance, you can use it to handle incoming web requests and send responses to the user. @app.route is a decorator that turns a regular Python function into a Flask view function, which converts the function’s return value into an HTTP response to be displayed by an HTTP client, such as a web browser. You pass the value ‘/’ to @app.route() to signify that this function will respond to web requests for the URL /, which is the main URL. Once you create the app instance, you use it to handle incoming web requests and send responses to the user. The Flask Mega-Tutorial (Python Web Development)
This in-depth tutorial series covers everything you need to know about Flask web development. It walks you through building a complete web application step-by-step, from the basics to advanced features.
More opportunities for you to learn
We’ve added 500+ learning opportunities to create one of the world’s most comprehensive free-to-degree online learning platforms. When beginning to learn Flask, it can be difficult to distinguish the micro-framework from its larger counterpart, the Django web framework. This course will teach you some of the advanced development concepts used in the top tech companies today. Because I’ve been leading tech teams in both large enterprise as well as startup companies in New York City for the past 15 years. Both are highly recommended in case you are learning to develop web applications.
This role may require knowledge of additional frameworks which can be acquired through a Flask boot camp, as well as specific educational milestones such as a bachelor’s degree or a master’s degree. Yes, Flask and Django both are Free Open Source, Python-based web frameworks that are used for building web applications. A list of best courses to learn programming, web, mobile, chatbot, AR/VR development, database management, data science, web design and cryptocurrency. The course starts with the basics, including Python fundamentals, programming, and user interaction. Then you will move onto how the internet works, making web requests and parsing webpages to get data from them using Python. This course will guide you in creating simple, intermediate, and advanced REST APIs including authentication, deployments, caching, and much more.

Finally, you will learn about web scraping, which is one of the most interesting things you could do in Python. It will build a web scraper right from scratch writing the code with a line-by-line explanation. Basic knowledge of Python, HTML, and CSS are prerequisite for this course.
- Flask developers possess adept coding skills and specific Python expertise.
- Scalable Web Applications with Python, Flask, and SQLAlchemy
Learn how to build scalable web applications using Python, Flask, and SQLAlchemy, git, and Heroku With Awesome Project.
- Message is actual text to be displayed and category is optional which is to render any error or info.
REST APIs with Flask and Python
Learn to build professional REST APIs with Python, Flask, Docker, Flask-Smorest, and Flask-SQLAlchemy. This course covers connecting web or mobile applications to databases, implementing authentication, logging, caching, and more. By the end, you’ll be able to create secure and reliable REST APIs for your applications. This tells Flask to take the value from the URL and pass it to the view function. The URL variable passes a keyword argument to the capitalize() view function. The argument has the same name as the URL variable (word in this case).

Scalable Web Applications with Python, Flask, and SQLAlchemy
Learn how to build scalable web applications using Python, Flask, and SQLAlchemy, git, and Heroku With Awesome Project. To display user data safely, use the escape() function that comes with the markupsafe package, which was installed along with Flask. This course will help you get started with Python web development. Currently your application only displays a simple message without any HTML. Web applications mainly use HTML to display information for the visitor, so you’ll now work on incorporating HTML files in your app, which can be displayed on the web browser.
- You use the python command line interface with the option -c to execute Python code.
- These packages are dependencies Flask needs to perform different functions.
- The method should be restarted manually for any change in the code.
- It covers using WTForms and SQLAlchemy in Flask applications, working with templates, and using SQLite with Flask.
- The concepts that are covered go well beyond Flask, including a wide range of topics Python web developers need to know when writing their own applications.
Then we’ll learn how to create forms to accept user information, how to save that information to a SQL database, and relay it back to the user. Flask provides a render_template() helper function that allows use of the Jinja template engine. This will make managing HTML much easier by writing your HTML code in .html files as well as using logic in your HTML code. You’ll use these HTML files, (templates) to build all of your application pages, such as the main page where you’ll display the current blog posts, the page of the blog post, the page where the user can add a new post, and so on. In this step, you’ll add a few routes to your application to display different pages depending on the requested URL. This course assumes that you are comfortable with the basics of Python such as variables, data types, functions and so on.
You’ll add a link to the style.css file inside the section of the index.html template file:
You will learn how to use Python and the Flask framework to build a backend for interactive web apps. By the end of this course, you will be able to write code for a Flask web application. In this course, you will learn the basics of web development with Flask. You will learn how to work with web forms; integrate Flask-Security, which allows you to add common security mechanisms; and create and test REST APIs using Postman.
