Python is a general-purpose programming language that supports Functional Programming, Object-Oriented Programming (OOPs), and Procedure Programming. If we concern about today's technologies, then Python is the best one out of the market. We can use python in so many applications including Web Development.
In this article, We'll see what is the framework, and which are the top frameworks in python? But, before we proceed on this let's look python's application in today's world.
Applications of Python programming -
- Web Development
- Machine Learning
- Cryptography
- Data Structure
- Games
- Data Science
- Computer Vision
- Artificial Intelligence
- Web Crawler
- GUI-Based Desktop applications
What are the Frameworks in Python?
The framework is a collection of modules or packages which help in writing web applications. Developer's work with help of the framework is quite easy as it provides the structure for applications.
Frameworks automate the implementation for general solutions which gives the flexibility to developers to focus only on the application's login instead of a routine process. The web application that uses frameworks works faster, reliable, scalable, and easily maintainable.
If you want to know What is API? What is REST Framework? and What is REST API? then you can refer this article.
Operations that the frameworks provide:
- URL Routing
- Input from handling and validation
- Output format with Templating Engine. (HTML, XML, JSON)
- Database Connection and Manipulation using ORM Mappers
- Web Security
- Session Storage and Retrieval
Top 5 Python Web Frameworks
1. Django
Django is a full-stack free open-source high-level Python web framework that includes all the necessary features by default. Making complex database-driven web applications easy is the primary goal of Django. We can build web applications fast and in an easy way with Django.
I already talked about Django in my previous articles. So today, we focus on other frameworks. Still, you can refer to Django REST Framework and Django Social Authentication articles to know more about it. (These articles also includes Code)
2. Web2Py
Web2Py is a full-stack scalable python web framework. It does not support Python 3.x, unfortunately. The interesting thing is that it has its own Web-based IDE, a separate code edition, a debugger, and one-click deployment as well.
Features -
- No requirements for installation and configuration
- Ability to run on different platforms
- Ability to read multiple protocols
- Provides Data Security that also prevents such
vulnerabilities like cross-site scripting injection flaws and malicious file
execution.
- It has an error tracking system through error logging
- The ability for role-based access control
3. Flask
Flask is a micro-framework that uses Unicode. The difference between the full-stack framework and micro framework is the full-stack framework does the heavy lifting for the application that we are making but the micro framework is small and very easy to use. Also, when we are using micro-framework the URL routing is going to be restful for many of the occasions.
Features -
- It is lightweight
- A modular design which makes it easily tractable
- It Has a fast debugger and a built-in development server
- Has restful request dispatching and integrated support for
unit testing
- It has secure cookie support
- Supports Jinja 2 templating
(Jinja 2 is a modern-day templating language that made after the Django's template language)
4. Bottle
The Bottle is also a micro framework that originally meant for building APIs. Bottle implemented everything in a single source file. Apart from the python standard library, it has no dependencies.
The default features are -
- Routing
- Templating utilities
- A basic abstraction over the WSGI standard
If you want to build simple personal app or prototyping learning web framework, then Bottle is a perfect solution.
5. CherryPy
CherryPy is an Open source minimalist web framework. It used to make building Python web applications. It allows us to use any type of technology for templating data access and so on.
However, it's still able to handle sessions, statics, cookies, file uploads and everything else that of web framework typically can.
Default features -
- Has an HTTP compliant WSGI thread pooled web server
- It has the simplicity of running multiple HTTP servers at
once.
- A powerful configuration system
- A flexible plug-in system
- Out-of-the-box tools for caching and coding sessions,
authentications, static content, and etc.
- Ability to run on different platforms.
Will look forward to read more from you!! Make sure your content has the latest info along with instructiveness. So get ahead with AWS elemental link service providers.
