Python is on an unexpected upward movement. And, the demand is sure to continue with no sign of dampening anytime soon. Python is expected to overtake Java and C# in the coming years, which is a clear indication of a lot more to come. Many of today’s big tech companies such as Google, Netflix, Instagram, are selecting Python frameworks for web development.
According to the Popularity of Programming Language Index, “python grew the most over the last five years by 19.0%. The TIOBE index puts python web application development at the 3rd place among the most used languages in the world”
Python gives a wide scope of frameworks to developers. There are two types of Python frameworks – Full Stack Framework and Non-Full Stack Framework. The full-stack Python frameworks give full support to developers including basic components like form generators, form validation, and template layouts.
Since Python does not accompany the built-in features required to accelerate custom web application development, many developers choose Python’s robust collection of frameworks to deal with the subtleties of execution.
Rather than writing similar code for every project, Python developers can use ready-made components in the framework. This not only saves time and money but even reduces time-to-market.
Python is an object-oriented, powerfully composed, interpreted, and interactive programming language. It’s easy-to-learn and easy-to-read feature effectively lessens the development time.
Ask any Python developer — newcomers or the skilled ones— they’ll agree on its reliability and efficient speed. Developers can work with and deploy Python frameworks for web development.
