What is Python?

Python is an open source and high-level programming language designed by Guido van Rossum. Released in 1991, this programming language’s design philosophy aims at code readability, which is why it’s one of the easiest languages to learn.

In addition, Python is an object-oriented, reflective, functional, procedural, and structural language. All these approaches of Python help programmers write logical and clear code for projects of all scales.

As of now, there are three major versions of Python, Python 3 being the latest. It also supports a wide range of libraries to simplify writing the code.


Python’s features are:

  • Open source and free: Python is open source, and you can download its code for free to use and modify it for your projects.
  • Easy to learn: Python is becoming popular because it’s easy to learn compared to other languages. Its simpler syntax uses plain English with less complexity. Hence, it’s developer-friendly and easy to code.
  • Extensive libraries: Python’s standard library is extensive with rich modules and functions that help you complete your projects faster instead of writing code from scratch. You can find reusable code for processes like image manipulation, unit testing, CGI, and more. Examples include Django, Flask, NumPy, and SciPy.
  • Extensible: Python is highly extensible with different modules to extend the core functionality. For example, you can add a programmable interface to an existing application.
  • Object-oriented: Python uses object-oriented programming concepts, such as objects, classes, inheritance, data encapsulation, and more.
  • Interpreted and easy to debug: Python executes code linearly, like Java, C, and C++. This way, there’s no need for compilation, and debugging becomes easy.
  • Dynamically-typed: Specifying a variable type such as char, int, double, etc., is not needed in Python as it’s decided during code run time rather than at the start. As a result, it makes programming simpler and reduces many lines of code.
  • Portable: Python uses portable code. So, you can use the same code across different platforms like Windows, macOS, Unix, or Linux.

Did you know that Python is the second most popular programming language (right behind JavaScript)? 🤓 

Where Is Python Used?

Python is a versatile programming language. You can use Python for a variety of purposes, including:

  • Web development: Due to its efficiency, speed, and other positive aspects, Python is excellent for web development. With the availability of extensive libraries like Django and Flask, the process becomes much more manageable. Some popular companies using it for this purpose include Instagram, Reddit, Uber, and Spotify.
  • Software development: Using Python, you can create software programs and applications running on your devices. Many Python packages, such as NumPy, Tkinter, SciPy, etc., simplify the software development procedures. You can also develop complex apps with scientific and numeric computing. A few biggies who use it for software development include Dropbox, PyChess, BitTorrent, Gramps, etc.
  • Machine learning and artificial intelligence: From search engines and social media to chatbots and virtual assistants, algorithms are everywhere and powered by machine learning and artificial intelligence. Python’s exclusive libraries, such as SciPy, Seaborn, TensorFlow, NumPy, Pandas, etc., serve these purposes.
  • Data Science: Python is used extensively in Data Science. It has plenty of related libraries and frameworks such as PyBrain, Bottle, Flask, web3py, etc., useful in data science to visualize and analyze large volumes of data and other purposes. It also helps in web scraping, which has become quite essential these days for businesses.
  • Creating desktop GUIs: Due to Python’s modular structure, it works on various operating systems and lets you build desktop GUIs utilizing an efficient framework, module, or text processor, such as PyGUI, PyGtk, PyQt4, PyQt5, etc.
  • Game development: You can develop games using Python libraries like PySoy (a 3D game engine based on Python). Games developed using Python are Disney’s Toontown Online, Battlefield 2, Frets on Fire, etc.

4 Benefits of Learning Python

Learning Python has several advantages for your career prospects. Let’s find out the answer to the question, “Why learn Python”?

1.Efficient in Development

Python is not only easy to learn and code, but it also accelerates the entire development process. It has a wide range of frameworks, packages, libraries, and modules that don’t require you to do everything from scratch.

You can also utilize reusable code to write the code faster with stability. It helps you automate standard processes and save time to focus on the logic and other vital aspects of web and software development.

2. Extremely Versatile

Python is a highly versatile language, which is one of the reasons behind its popularity and high usability. From small- to large-scale projects, Python works with the same efficiency. Apart from the uses mentioned above, developers use it for deep learning, data engineering, process automation, the Internet of Things (IoT), and more.

That said, its versatility could be due to the massive number of functions, methods, frameworks, and libraries it supports. And Python’s readability, popularity, and usability have further encouraged many more libraries, making the language more user-friendly.

3. Demand for Python Developers

The demand for Python developers is increasing in the market with its popularity and usage in emerging technologies. It finds use in business services, insurance, aerospace, retail, banking, finance, info-tech, consulting, healthcare, and hardware, just to name a few.

The top companies using Python are Google, NASA, YouTube, Quora, IBM, HP, Qualcomm, and Dropbox. And they also hire Python developers frequently.

In 2021, the average salary of Python developers in the US is $110,840 annually. So, learning Python can be rewarding for your career.

4. Supportive Community

Although there’s official Python documentation available, sometimes you may get stuck, especially if you are a beginner. At this time, a supportive community is something that can help you. Fortunately, Python has a vast community of developers you can turn to in case of doubts or questions.

You can find online forums such as Stack Overflow, open source communities, and local meet-ups to explore the language. In addition, there are lots of courses, tutorials, websites, and other resources dedicated to Python (some of which we’ll discuss in this article).
