Python is undoubtedly most popular high level programming language which is ideal for scripting as well as web applications.
The easy syntax and easy deployment of apps just work like charm in python.
Pythons easy syntax allows programmers to build their projects faster and be creative with the degsin and alogirthm of the application rather than getting stuck in syntax errors.
Also python is modular language it provides different modules for each purpose which are really handy!!
While developing web application pythons framework play major role.
So, first question is...
What is Framework?
A framework supports the development of an application, incorporating resources, APIs, and web services.
Basically it is tool kit which contains every tool for the purpose for which it was made.
What is Web Framework?
A web application framework, a Web Framework automates overhead linked to different tasks involved in the web development, which further allow developers to pay attention to the app logic instead of routine jobs. In general, there are three types of Python web frameworks: full stack (offers complete support), micro (comes with limited features and functionalities), and asynchronous (relies on Python’s asynchronous input/output library)
What are available Web Frameworks in python?
Django (Full-stack framework)
Flask (Micro framework)
Tornado (Asynchronous framework)
Web2py (Micro framework)
Bottle (Micro framework)
CherryPy (Micro framework)
Falcon (Micro framework)
Pyramid (Full-stack framework)
Hug (Micro framework)
TurboGears (Full-stack framework)
Let's get in depth about each.
Django
This free open-source Python's framework is scalable, flexible, fast, and versatile. It comes up with several built-in features that help it to develop small and complex web applications. To map objects with the databases, this framework uses object-relational mapper. In short, it is one of the prime frameworks for backend development. Django uses PostgreSQL, Oracle, and SQLite databases.
Features:
URL routing
Template engine
Data schema migrations
Authentication
ORM or object-relational mapper
Flask
Available under the BSD license, Flask has a built-in debugger and development server. The light-weight module and modular design of the framework makes it a perfect choice for the developers who are looking out a solid web application foundation. It is the second most used framework after Django.
Features :
Jinja2 templating
Fast debugger
WSGI 1.0 compliance
Include plugins to support any ORM
Unit testing support
HTTP request handling
Unicode-based
RESTful request dispatching
Tornado
Tornado focuses on speeding up the development process and also has the potential to deal with huge traffic. By using a non-blocking network I/O, it can fix the C10k problem. If you configure this open-source web framework properly, it is capable of handling can more than 10,000 concurrent connections. In short, Tornado is created to be scalable and deal with asynchronous processes.
Features:
Support for user authentication
In-built HTTP server
Web templating language powered by Python
Excellent performance
Real-time services
Support for Interpretation and Localization
Web2py
Web2Py is a full-stack open-source framework that has a personal Integrated Development Environment. This IDE further comprises a code editor, a specialized tool for one-click deployment, and a debugger. Using these tools, developers can build and debug a code while testing web applications. To detect bugs in the applications, it comprises a cross-platform web app framework, which further includes a ticketing system and maintenance support.
Features:
Hassle-free database connectivity
Compatible with cross-platform
Internalization support
Backward compliance
Default support for cookies, HTTP response handling, and sessions
No requirement for installation and configuration
High data security to prevent common vulnerabilities
Bottle
Mainly built for creating APIs, this micro-framework implements everything in one source file. Bottle is a perfect framework for developing small apps with not more than 500 lines of code and no other needs. It is a fast and simple framework that offers adaptor support for WSGI/HTTP servers along with the third-party engines.
Features:
Comes with an HTTP server
Database plugins support
Third-party template engine support
Easy access to create data and file uploads
Lightweight
No dependencies apart from Python standard library
Clean and dynamic URLs
CherryPy
CherryPy is a minimalist framework that is designed to be extensible. Applications developed with the support of this framework can run on any OS that supports Python. The framework allows developers to use any type of technology for data access and templating.
Features:
A powerful configuration system
HTTP/1.1-compliant WSGI thread-pooled web server
Highly advanced tools for authentication, caching, encoding, and other activities
Support for testing, coverage, and profiling
Can run on PyPy, Jython, Python 2.7+, Android, and Python 3.1+
Falcon
If you want to build back ends in a short time, then Falcon is a perfect framework. The framework makes it easy for the developers to create cleaner designs and respond to more number of requests. It never stops a developer to select libraries to be used for authorization and databases.
Features:
Full code coverage with an advanced test suite
Hassle-free access through response and request classes
Highly optimized code base
Upfront exception handling
Built-in URI templates for intuitive routines
Idiomatic HTTP error responses
Pyramid
It is the one of the most preferred open-source Python frameworks that helps developers to accomplish complex tasks with ease. The framework makes writing web applications simpler and smoother. It works well in all the supported versions of Python.
Features:
Renderers
Single-file application
Predicates
Testing, support, and comprehensive data documentation
Function decorators
URL generation and more
Hug
This API development framework is designed to allow developers to craft an API once and then use wherever and whenever required. It offers multiple interfaces and hence, simplifies and speeds up API development.
Features :
Annotation-powered validation
Serves as a python library
Code once and use anywhere
Auto documentation support.
TurboGear
This framework was built from best-of-breed components to offer a fully-customizable web server gateway and make the most of the new components. TurboGear is a data-driven open-source web application development framework that has a built-in templating engine and a flexible object-relational mapping.
Features:
Multiple database support
Pylons as a web server
Built-in support for SQLAlchemy and SQLObject
MVC-style architecture
PasteScript templates
Command-line tools
Conclusion
Python frameworks offer developers a structure for application development, which in turn reduces their efforts and minimize the development time. These frameworks include various modules and packages to write web applications without the requirement of process management. Hope this article helped you to know about the ten most-used frameworks
