As technology advances, the technological world undergoes rapid change. The days when a developer can easily keep a job with only one programming language for years without picking up new skills are long gone. Many of us enter the world of programming and web development knowing only one or two technologies, like Java, C++, or javascript, but that is no longer enough.
Before now, web developers used to work in groups on specialized projects, such as front-end development carried out by a different team of programmers and back-end development written by a different team of programmers, also referred to as server-side developers.
Nowadays, everyone is looking for full-stack developers, someone who is knowledgeable in both front-end and back-end technology and can work independently to develop a fully functional web application.
Two ways that people can use a computer to make websites are Django and Flask. Web developers use two different programs to create sites and web apps. These two programs are called frameworks, and they help people make fun, cool sites that look nice and run fast. Django is one of the top frameworks because it is open source and works well. But you must learn about web apps to build different web pages and website templates. You will need to create different apps from scratch to develop a single web app. The second way, Flask, is simpler and easier.
Flask is a newer framework that is easier to learn for building simple web apps. That is a lovely place to start learning web development.
That is why you should be happy that you are on this journey to learn how to build websites and web apps with Flask and Django. Two in one!
Learning a framework that complements your primary area of expertise is preferable. For example, a Python developer would learn more from Django and Flask than from Angular. Similarly, a javascript developer would learn React and Node JS better than Django and Node JS. This book is only for developers who are familiar with Python programming language.
