Coursera ranks it as the world’s most popular programming language.
For instance, let’s say you want to build a basic application that displays data in a tabular format. With the help of frameworks and libraries, you don’t have to write all the code from scratch. Instead, you can just import the module that does what you want and tweak it to your liking.
Plus, frameworks often provide useful features like data validation, security measures, and interaction with the database right off the bat. In other words, less time spent coding means more time available to focus on other parts of your project.
It goes without mentioning the convenience of dealing with less code. Not only do frameworks save you time, but they also make your code more consistent and easily manageable.
