Python Introduction to Web development using Flask

Flask is a small and lightweight Python web framework that provides useful tools and features that make creating web applications in Python easier. It gives developers flexibility and is a more accessible framework for new developers since you can build a web application quickly using only a single Python file. Flask is also extensible and doesn’t force a particular directory structure or require complicated boilerplate code before getting started. With instruction from online Flask courses, you can build intuitive websites for yourself or pursue a career in web development.

Is Python Flask easy to learn?

Flask is a micro web framework that is written in Python. Flask is very easy to learn, and also its implementation is straightforward. In just a few lines of code, you can get started with this. Flask is used in top tech companies also like: Netflix, Reddit, Mozilla, and so on.

Flask’s lack of standard boilerplate via a commandline interface for setting up your project structure is a double edged sword. When you get started with Flask you will have to figure out how to scale the files and modules for the code in your application. The following open source projects range from simple to complex and can give you ideas about how to working on your codebase. The “Hello, World!” code for Flask is just seven lines of code but learning how to build full-featured web applications with any framework takes a lot of work. These resources listed below are the best up-to-date tutorials and references for getting started.


Python 2.6 or higher is required for the installation of the Flask. You can start by import Flask from the flask package on any python IDE. For installation on any environment, you can click on the installation link given below. Previously, Aakash has worked as a software engineer (APIs & Data Platforms) at Twitter in Ireland & San Francisco and graduated from the Indian Institute of Technology, Bombay. He’s also an avid blogger, open-source contributor, and online educator.

  • And, if you add a huge number of extensions, it may start to slow down the app itself due to a multitude of requests.
  • If you are using Git, it is a good idea to ignore the newly created env directory in your .gitignore file to avoid tracking files not related to the project.
  • On top of that it’s very explicit, which increases readability.
  • Flask skills are transferable to a number of web developer and computer science roles, including Flask developer, Python developer, and data scientist.
  • Individualized mentorship Nurture your inner tech pro with personalized guidance from not one, but two industry experts.

Flask is a Python module that lets you develop web applications more easily than developing from scratch. It draws from Werkzeug, a Web Server Gateway Interface toolkit, and Jinja2, an HTML template engine. As a micro-framework, Flask keeps its fundamental application simple and offers a range of extensions with additional capabilities.
