What is Node.js?
Check out upGrad’s Advanced Certification in Cloud Computing
It was invented by Ryan Dahl in 2009 to be used in Google Chrome. Node.js is compatible with Mac OS X, Microsoft’s Windows, and Linux operating systems. It is better suited for web applications and web development. Data streaming applications, JSON APIs based applications and Data Intensive Real-time Applications (DIRT) are some of the most suitable applications for Node.js.

- Node.js eliminates the need for buffering as the output data is segmented in pieces.

What is Python?
Python is a high level, interpreted popular programming language that is widely used in backend development. It is an object-oriented, multipurpose language that supports dynamic typing, making it faster, reliable and simpler to use. Python’s close to human language syntax makes it an ideal language for scripting.
It was invented by Guido van Rossum in 1991 and primarily runs Google’s App Engine. Since Python is an interpreted language, its execution takes longer but this results in a faster and more efficient development process. Python supports functional programming, Object Oriented Programming as well as procedural programming.
- It is an open sourced language and has the largest community of all programming languages
- Python has extensive libraries for analysis, testing, etc that make writing codes using it efficient and faster
- Python can be integrated with C#, Java, COM, ActiveX, and several other programming languages
- Python code is not made computer-readable code at runtime. It is interpreted
- Multiple programming patterns are possible with Python
- Python’s interpreter can include low-level modules that facilitate customisation of tools.
- Python is the leading language for back-end development, performing numerical calculations and implementing machine learning. Learn more about Python.

What are the major differences between Node.js and Python?
|Although Python is not event-driven or asynchronous, it can be made so with the help of additional tools like asyncio.||Node.js is event-driven and supports asynchronous programming. This also means it is a non-blocking model where no process gets blocked and is called immediately as the event occurs.|
|Performance and Speed|
|Since Python is a single-flow interpreted language that supports dynamic typing, the execution is much slower in comparison.||Node.js code is interpreted by V8, known for its high speed, and is executed outside the web browser, its performance is faster and more efficient. Also, since Node.js is non-blocking and even driven, and is cache-enabled, this facilitates faster execution.|
|Python is suitable for larger projects since its scripting is far more efficient.||Node.js is recommended for smaller projects.|
|Python can be integrated with development tools and frameworks like Django, Flask, Pyramid, Web2Py, or CherryPy.||Node.js is highly extensible. It can be customised and integrated with a variety of tools such as Babel, Jasmine, Log.io, Migrat, PM2, Webpack, etc.|
|Python is most suitable for web (backend) development; it is the ideal framework for machine learning, artificial intelligence, big data solutions, government projects and data analysis.||Because of Node.js’ event-based model, it is best suited for providing IoT solutions, creating real-time chatbots and messengers, and building single-page apps.|

Similarities between Node.js and Python
While there are several differences between Node.js and Python, the two frameworks also share some similarities.
- Node.js is packed with one of the largest software library repository that is managed by NPM (Node Package Manager)
Managed by Pip (Pip installs Python), Python packages and libraries are also extensive. They are extremely fast and easy to use.
- Both Node.js and Python can be used for back-end development and front-end development. They are also cross-platform frameworks, meaning an application or program written on one operating system will work on another as well.
- Both Python and Node.js have a large and active community of developers having varied levels of experience. Since Python is relatively older, its community is significantly larger than Node.js’. In any case, business owners and developers alike can benefit from these open-source platforms.

What is Django and what are its features?
Django is an open-source backend web framework developed in python that helps in fast development of applications. The advantage of using such a framework is that one doesn't have to manually write the code for authentication, file upload, etc. but can directly use the framework provided by the various libraries and modules in Django. Django can be integrated with various client-side frameworks and also provides templates for different functionalities making it versatile. It uses cryptographic hash functions to ensure security. It follows the DRY principle i.e. Don't Repeat Yourself. Some popular applications that use Django are Instagram, Bitbucket, Mozilla, Spotify, etc.

What is meant by event-driven programming?
A program that executes when an event occurs and responds to the actions of the user is called an event-driven program. Events could be keystrokes, mouse clicks, etc. An event-driven application has to regularly monitor the user actions and might include sensors that continuously detect the state changes. These applications are very flexible and additional functionalities can be implemented and integrated easily into the existing application. In an Event-driven architecture, event producers produce events and send them to the event broker which in turn interacts with the event consumers based on what they want to consume.
