What Is Python?

With dynamic semantics, Python is an interpreted, high-level, general-purpose programming language. It utilizes an object-oriented approach and is frequently utilized for backend development. Dynamic typing, built-in data structures, dynamic binding, and other features make Python the ideal tool for Rapid Application Development (RAD). Additionally, it is utilized as a scripting or glue language to connect the already existing parts.

Pros of Python

  1. Encourages code reuse and modularity
  2. High-level built-in data structures
  3. Extensive libraries
  4. Smooth learning curve
  5. Large global community
  6. Portable and versatile
  7. DevOps tools
  8. Process and test automation
  9. The language of IoT
  10. Deep learning, ML, and AI libraries

Cons of Python

  1. Speed issues
  2. High memory consumption
  3. It doesn’t support multithreading
  4. Hard to read functional programming
  5. Design restrictions

Use Cases of Python

  1. Instagram builds its backend and scales its service infrastructure.
  2. Google uses Python because it is simple, fast, and easy to deploy.
  3. Spotify uses Python to speed up development, build backend services, and analyze data.
  4. Python is preferred by Quora due to its readability, ease of code writing, and availability of numerous frameworks like Pylons and Django, among others.
  5. Python is chosen by Industrial Light and Magic (ILM) due to its ease of interoperability with C++ and C, as well as its assistance in developing effective production pipelines and expanding existing applications.

Node.JS Vs. Python: Which One Should You Choose For Your Startup?

One of the most important factors determining your project’s success is your comprehension of the functional requirements. You can use these criteria to choose the best backend technology for your project once those are clear:

1. Architecture

Node.js is an event-driven runtime environment capable of performing non-hindering I/O tasks. It can handle thousands of requests simultaneously without switching thread context. Because of these features, Node.js is the best choice for real-time web applications like chatbots and gaming applications.

On the other hand, Python has a synchronous architecture that slows down performance and speed. However, Python development services can use modules like CPython and libraries like Ayncio for parallel processing and event-driven projects.

2. Syntax And Learning Curve

The syntax of Python is fairly straightforward. The code is easier to debug and comprehend because it has fewer lines. Python can be used by any developer with a strong technical background quickly.

As the syntax of Node.js and JavaScript is identical, Node.js is frequently simple for developers who have previously worked with JavaScript.

3. Speed And Performance

Node.js offers high speed and performance because it executes the code outside the client’s browser and has a non-blocking architecture. Additionally, because Node.js lets you cache retrieved data, apps become more responsive and take less time to load.

Python is slower than Node.js because it does not support multithreading. In this manner, Python will only be a decent decision if your task frequently needs to review information from the web servers.

4. Libraries

The default package handler for Python packages and libraries is Pip. There are over 220,000 Python packages for image processing, computation, data science, and other fields.

Node.JS libraries and bundles are taken care of by the Node package manager or NPM, with over 1.3 million well-documented and simple-to-utilize bundles.

5. Scalability

Python lacks scalability because it uses GIL, or Global Interpreter Lock, and does not support multithreading. Python is a slow programming language because it is also an interpreted language.

Node.js is highly scalable as it supports multithreading and comes with a cluster module that can handle the machine’s full processing power. By adding new nodes and more resources to the system, node.js development companies can scale their apps vertically and horizontally with Node.js.

6. Error Handling

To provide your customers with a better user experience and write clean and reusable code, it is essential to have a robust error-handling system. Because of its concise syntax and clean, readable code, Python handles errors more effectively. As a result, errors can be fixed and troubleshooted in less time. You can also take the help of a python development company to ensure more productivity for your startup company.

Node.js can debug fallacies, yet it becomes hard to do so when various solicitations are handled simultaneously to accomplish elite execution with multithreading.

7. Community

Python and Node.js have large and active communities where peers can find support and online resources.

They provide excellent opportunities to collaborate with developers worldwide with varying experience and expertise in their community forums. Node.js and Python are open to contributions from skilled developers worldwide, including their packages.

8. Extensibility

Can easily extend both Python and Node.js. Frameworks in Python, such as Flask, Robot, Django, CherryPy, and others, are available to developers, along with APIs to improve the language’s capabilities and features.

Using frameworks like Meteor, Fastify, Hapi, and others can use the built-in APIs of Node.js to expand its functionality, Testing systems like Jasmine and others.
