Python is a high-level, interpreted programming language. Python is quickly ascending to the forefront of the most popular programming languages in the world. Python is a general-purpose programming language, so it can be used for many things. Python is used for web development, AI, machine learning, operating systems, mobile application development, and video games.
Python in Real-World
Python is used in every industry and scientific field which you can imagine as follows:
- Web Development
- Game Development
- Machine Learning
- Data Science
- Computer Science Education
- Biology and Bioinformatics
- Neuroscience and Psychology
- Computer Vision and Image Processing
- Medicine and Pharmacology

Python offers pre-built libraries and frameworks such as Pyramid, Django, and Flask; web applications can be developed rapidly. Python is a go-to for complex web development projects, as its flexibility makes it possible to create sophisticated web utilities with relative ease.
Python Frameworks provides unparalleled security, scalability, and convenience as compared to building websites from scratch.Giant websites and platforms like YouTube and Google rely heavily on Python for critical infrastructure. This has further enhanced its reputation as a solid component in the web developer’s toolkit.
Interactive games can be built with Python; it provides functionality and libraries for game development. Some popular games like EVE Online and Pirates of the Caribbean were created using Python. There are libraries and frameworks such as Pygame, Pyglet, and PyOgre to help you create your own games in Python.By using the
Pygame module, you can control the logic and graphics of your games without worrying about the backend complexities required for working with video and audio.
Entire development platforms with every tool you need including editors, animation, render engines, export functionality, etc. Python is sort of stuck in the middle ground in this regard. Yeah, Pygame is okay. But that’s just it, and okay isn’t the best.Most people who are looking to create a serious career in the gaming industry will choose C# or C++ instead, using Python for hobby projects and understanding the concepts of coding.
Machine learning is a type of artificial intelligence (AI) that provides computers with the ability to learn without being explicitly programmed.Python is used for machine learning via specific machine learning libraries and frameworks including scikit-learn and TensorFlow.Machine Learning is simply making a computer perform a task without explicitly programming it. In today’s world every system that does well has a machine learning algorithm at its heart.
Take for example Google Search engine, Amazon Product recommendations, LinkedIn, Facebook etc, all these systems have machine learning algorithms embedded in their systems in one form or the other. They are efficiently utilising data collected from various channels which helps them get a bigger picture of what they are doing and what they should do.
Now let’s understand why would anyone want to use only Python in designing any Machine Learning project. Machine learning, in layman terms, is to use the data to make a machine make intelligent decisions. For example — You can build a spam detection algorithm where the rules can be learned from the data or an anomaly detection of rare events by looking at previous data or arranging your email based on tags you had assigned by learning on email history and so on.
Python can be easily integrated with other programming languages. The applications built using Python are easily scalable and future-oriented. All the above-mentioned features of Python makes it important for the data scientists. This has made Python the first choice of Data Scientists.Python is an object-oriented, open-source, adaptable and simple to learn programming language. It has a rich arrangement of libraries and tools that makes the assignments simple for Data scientists.
As per a survey by industry analyst O’Reilly, about 40% of data scientists use Python in their day-to-day work for computing, analyzing and reporting of data. Big organizations such as NASA, Google, and CERN also use Python for almost every purpose of programming.
In many scenarios, Python is the programming language of choice for the daily tasks that data scientists tackle, and is one of the top data science tools used across industries. For data scientists who need to incorporate statistical code into production databases or integrate data with web-based applications, Python is often the ideal choice. It is also ideal for implementing algorithms, which is something that data scientists need to do often.

Together, these tools are increasingly opening possibilities for development, sharing and building upon experimental and analysis code.
Computer Vision and Image Processing
Computer vision is the automated extraction of information from images. Information can mean anything from 3D models, camera position, object detection and recognition to grouping and searching image content.When programming computer vision we need representations of vectors and ma-trices and operations on them. This is handled by Python’s NumPy module where both vectors and matrices are represented by the array type.
OpenCV is the most popular library for computer vision. Originally written in C/C++, it also provides bindings for Python. OpenCV is a C++ library with modules that cover many areas of computer vision. Be-sides C++ (and C) there is growing support for Python as a simpler scripting language through a Python interface on top of the C++ code base. The Python interface is still under development and not all parts of OpenCV are exposed and many functions are undocumented.
Medicine and Pharmacology
Python has played its amazing role in the medical field. It's really a wonder for us to know how technology is being combined with medical knowledge to provide accurate and efficient diagnoses and treatments to patients.Some examples of the use of Python in medicine and pharmacology are here:
