Python is a powerful, high-level programming language that can be used for web development, operating systems, AI, machine learning, numerical computing, mobile applications, and game development. The recent surge in the use of Python is largely due to its simple syntax and ease of use, which makes it relatively easy to learn even by beginners and non-programmers.  

Python was originally developed by Guido Van Rossum in the early 1980s and continued to be used in a wide variety of domains in the tech industry. With the introduction of Python 2.0 in the early 2000s, the language evolved into its modern form while retaining its basic operational principles. Python uses object-oriented programing, which is perfect for large-scale applications of Python as well as for small programs.

Top 7 Practical Applications of Python

Operating Systems

The robust standard library of Python makes it perfect for building entire operating systems. The object-oriented design of the language ensures large projects are easily managed. Python is compatible with most operating systems and can be easily used to build native applications for Windows and Mac computers. 

Web and Internet Development

Python offers several choices for complex web development projects. HTML and JavaScript are the main languages used to build the front end of an application. But Python-based web frameworks like Django, Pyramid, and Flask are used to handle backend or server-side functionality of sites and services like Spotify, Reddit, and Mozilla. Giant platforms like Google and YouTube depend largely on Python for critical infrastructure. 

The standard library of Python also supports many Internet protocols like HTML and XML, JSON, Email processing, FTP, and IMAP. 

Game Development

Just like for web development, Python offers an array of tools and libraries for game development. Would you believe, Battlefield 2 – one of the most popular shooting games of the early 2000s, was developed with the use of Python

Python’s 2D and 3D game development libraries are PyGame, Pycap, Panda#D, Construct, PySoy, and PyOpenGL.

Python has been used to develop popular games, including Sims 4, World of Tanks, Eve Online, Mount & Blade, Doki Doki Literature Club, and Disney’s Toontown Online, to name a few.  

Scientific and Numeric Computing

The Python ecosystem offers numerous tools and libraries that help scientists and researchers in scientific and numeric computing.  

  • SciPy is a set of packages for mathematics, science, and engineering 
  • Pandas is a library used for data analysis and modeling
  • IPython is a strong interactive shell that provides hassle-free editing and recording of a work session and aid in visualizing and parallel computing. 
  • FreeCAD and Abaqus are real-life numerical and scientific applications built with Python

Artificial Intelligence and Machine Learning

The hottest buzzwords of the decade – Artificial Intelligence (AI) and Machine Learning are mostly about algorithms, code, and logic. Python, along with a few other programming languages, is increasingly being used for developing AI and ML-powered solutions. The scope and power of Python, along with its stability and security, make it ideal for running AI and ML systems. 

Some important libraries for the job are:

  • Scikit-Learn – for building various machine learning models
  • SciPy – for scientific and technical computing
  • TensorFlow – for state-of-the-art neural networks
  • Keras – for artificial neural networks
  • Pandas – for data analysis and manipulation  

Desktop GUI

Python is an excellent choice for desktop GUI (Graphical User Interface) programming. The language offers numerous options for developers to build a fully functional GUI. The comprehensive syntax and modular programming approach of the Python framework help create a super-fast and responsive GUI. 

Some prominent applications of Python tools for GUI development are PyQt, Tkinter, wxWidgets, Python GTK+, and Kivy. Standard applications like Dropbox and BitTorrent are primarily written in Python.  

Business Applications

Applications of Python also include building ERP and ecommerce systems. Business applications are different from typical consumer software because they offer a set of specific features instead of a variety of features. Besides, they target a very tight-knit user group, usually an organization. 

Python is perfect for delivering best-performance custom solutions for business applications as well as consumer applications. 

Odoo is a well-rounded management software that offers numerous business applications that constitute a complete set of enterprise management applications

Tryton is a three-tier high-level application platform designed for general purposes

Why Use Python in Web Development?

Technology giants such as Spotify, Instagram, and Google use the open-source, easy-to-understand Python programming language for developing enterprise-level, robust, and responsive web applications.

Packaged to expedite installation, the ActivePython software, with a comprehensive set of extensions, allows Python developers to start working with state-of-the-art Python frameworks such as Tornado, Django, and Flask within minutes.

Integrating the Python programming language, the ActivePython software package, offered via the ActiveState Platform, also permits users to connect to AWS (Amazon Web Services) API and SDK libraries. This heightens the appeal of the software, making it the preferred choice for web developers around the world.

Now, before we learn what is Python used for, here are the top advantages of using Python in web development.

Python is Easy to Learn

Compared to other programming languages like C++ or Java, the design philosophy of Python - emphasizing general expressions and code readability with significant use of whitespace - makes the programming language easy to understand, even for beginners. Additionally, developers using Python can get their job done by writing much less code.

Python Has a Rich Ecosystem

The extensive Python library offers a wide range of packages and tools, such as SLQALchemy, Pygal, Pandas, and Numpy, which allow developers to access pre-defined code, ensuring fast and smooth application development.

Speedy Prototyping

In comparison to programming languages like C++ or Java, Python reduces the development time to a great extent, making things easier for developers to build prototypes quickly and gain feedback on their projects.
