Top 20 Python Web Frameworks to Use in 2019
Python is a high-level, interpreted and dynamically-typed language that implements OOP (Object-oriented Programming Language) basic concepts.
It has a distinct syntax that makes it stand out amongst other programming languages like C, C++, and Java. Thus, it is easy and simple to learn.
Most Web Development Company developers use frameworks to develop apps and create code. Frameworks provide a definite structure to help the developer focus on the core app logic than on other things.
Python Frameworks requires a platform to code and while choosing it, you need to consider the complexity and size of your project or app.
Types of Frameworks:
Python Frameworks can be divided into two types:
- The frameworks that provide a one-stop solution for every requirement a developer can have are called full-stack frameworks. With a typical full-stack framework, you get form validation, template layouts, and form generators.
- Microframework and asynchronous framework are non-full-stack frameworks. Microframework doesn’t offer additional features and functionalities while the asynchronous framework is a type of microframework that let developers handles an immense set of in-sync connections.

The framework that you choose for your project obviously depends on the objective of your work and also on you.
Every framework has its share of cons and pros, but developers too have their own preferences and coding styles.
The success of your project might depend on what framework you choose, so choose the one most useful for you and your team.
