Uses of Python in Major Industries: The Ultimate Guide

Python is a high-level programming language that’s interpreted and supports object-oriented programming, making it easy to reuse code throughout your project. Many developers and software development companies adopt it. Hence, it has more uses for Python in major industries. In this blog, we will elaborate on the uses of python in real-world applications.

Why Python?  

When building an application, the first thing that comes to mind is selecting the best programming language or Framework. Before we find out what python is used for, we should raise a question about why we should use Python.

When selecting a programming language, it’s best to focus on its core features, including: 

  • Syntax
  • Compiler 
  • Library and Frameworks it supports. 

Python has a straightforward syntax, almost like the English language, making it extremely beginner friendly. In addition, it also makes it easier to find bugs in your code and code written by other developers. Its readability also helps developing teams focus on building rather than spending time understanding each other’s code. As a result, this decreases production time, and developers can make their applications scalable.

It has extensive documentation available on the internet with contributions from companies like Google. It makes the language dependable and future proof making it the first choice for most software developers.

Python has an extensive library and frameworks like Flask and Django, enabling its use in software engineering, web development, automation, etc.

Example Code

The following code snippet requires the Python compiler and flash library should be installed on the system.

from flask import Flask
app = Flask(__name__)

def hello():
    return 'Hello World!'

if __name__ == '__main__':


  • Line#1: We import the Flask library.
  • Line#2: The ‘Flask’ application object by the name of app is created to access the ‘Flask’ library.
  • Line#4–6: We create a route ‘/’ which redirects to a webpage, and we return the string ‘Hello World!’ which is printed on the webpage. 
  • Line#9–10: Part of the syntax needed to compile the code.
