Concurrency: when two or more tasks execute in multiple threads, but not at the same time.

These terms tend to confuse people, so let’s define them so that we can be on the same page: Concurrency and parallelismĪnother important aspect of choosing a backend is concurrency and parallelism. VerdictĮven though the language’s architectures are different, both languages are good choices and can support synchronous and asynchronous programming.

However, you can still leverage it using the asyncio package, which allows you to write asynchronous code with the async/await syntax since it implements the event loop, futures, etc. Unlike Node.js, Python is not based on an event-driven architecture. This behavior is what makes Python single-threaded. Even if the Python program uses multiple threads, the GIL will switch among the threads at regular intervals to give each thread a chance to execute code - but they cannot execute in parallel by default.

Python is also a single-threaded language, largely because it implements a Global Interpreter Lock (GIL), a mechanism that allows only one thread to take hold of the Python interpreter and run Python code at a given time. This behavior is what makes Node.js non-blocking because expensive tasks don’t block the main thread instead, they execute in separate libuv threads, and Node.js continues executing other parts of the source code. Node.js uses callbacks to signal the completion of long-running tasks, and once finished, they are added to a task queue before finally being added back to the main thread. It also makes use of other threads that the libuv C library provides to handle expensive or long-running tasks. It has a single thread where all code you write and the libraries you use executes. Node.js is single-threaded, non-blocking, and implements an event-driven architecture. In this section, we’ll take a bird’s eye view of both Node.js and Python architectures. Good architecture design can lead to systems that scale, perform well, and are maintainable.

Comparing architecturesĪ software architecture describes how major components in a system interact, relate, and are organized. Python is constantly evolving, and it has mature web frameworks such as Django, Flask, and FastAPI that you can also use in your backend development projects. Aside from that, big companies such as Google, Facebook, Dropbox, and Instagram use it for both their internal and external tools - even NASA has found applications for it. It was designed and developed by Guido van Rossum, and was released in 1991 to mainstream success Python has consistently ranked in the top 10 of the TIOBE Programming Community Index. Python is an interpreted, general-purpose programming language commonly used for scripting, backend development, machine learning, and data science, to mention a few. Over the years, it has grown and become a strong contender to older languages like Python, and offers a bunch of tools for backend development, such as Express.js, Fastify, and NestJS. Node was developed by Ryan Dahl and was released in 2009, becoming an instant hit as it allowed JavaScript developers to write JavaScript code outside the web browser for the first time. Node.js is multi-paradigm and supports the following paradigms: It is commonly used for building real-time applications, backends, and desktop and mobile applications. Node.js is an asynchronous JavaScript runtime that runs on Google’s V8 engine.

In this article, we will analyze the pro and cons of both Node.js and Python, and see the scenarios where one would be better than the other so that you can make the best choice for your backend. Both have very strong package ecosystems and communities and choosing between the two can be difficult. Node.js and Python are some of the most popular choices for backend development. After all, different languages have their pros and cons that you need to consider to make sure it is the right tool for the application you’re trying to build.

Python: How to choose the best technology to develop your backendĬhoosing a backend programming language is never an easy task. I hope by sharing my experience, others can learn something from them. I love learning new things, and writing helps me understand and solidify concepts. If the fastest programs are hand-written vector instructions, does the host language matter? You might be more interested in the less optimised programs - more seconds, less gz source code.Stanley Ulili Follow I'm a freelance web developer and researcher from Malawi.
