What is Python?

Python is a general-purpose and dynamically-typed language, supporting numerous programming paradigms. These paradigms involve functional, structured, and object-oriented programming. Initially released in 1991, Python focuses on code readability and syntax simplicity, helping software engineers faster create performant web applications.

It takes third place in the list of the most popular languages worldwide according to the TIOBE Programming Community Index. Python was also named the Programming Language of the Year in 2007, 2010, and 2018. On StackOverflow Developer Survey 2019, it was featured as the first most loved and the second most wanted language. As of today, Python is one of the best programming languages for 2020 and the years to come.

What are the main use cases of Python?

With multiple libraries and frameworks, Python coding language is perfectly suited for building innovative projects. Many startups choose Python for its high development speed, portability, and numerous functionality packages.

Python is mainly used in:

  • custom web development
  • data science and scientific computing
  • data analysis
  • information security
  • REST APIs (application programming interfaces)
  • artificial intelligence, which comprises machine learning, deep learning, natural language processing (NLP), text and image processing

Let’s take a deeper insight into the Python developer environment and use cases.

Python is a scripting language that has a modular architecture and contains text processing tools. Thanks to them, it is a great choice for building NLP (natural language processing) functionality.

Python is often used in information safety, involving exploit development. Exploit is a computer program or a piece of software that makes use of bugs or vulnerabilities. Programmers can create exploits to detect and showcase application errors.

Providing a fully customizable graphical interface made with pure Python, Immunity Debugger allows analyzing malware, automating the debugging process, and preventing corruption during complex analysis. Furthermore, it reduces exploit development time by 50%.

Using libraries such as Keras, Pytorch, and TensorFlow, Python lets software engineers build artificial intelligence and machine learning-based solutions.

With the help of SciPy, NumPy, and Pandas libraries, you can launch scientific computing and data analytics projects. Employing standard formats and protocols—for instance, MIME, HTTP, etc.—programmers can write web applications.

Thanks to SageMath—computer mathematical software—Python development teams can make systems that support complex calculations and formulas. Graph theory, science, algebra, number theory, statistics, numerical mathematics, etc. are those areas where you can use SageMath and Python.

The key benefits of Python programming language

1. Improved time-to-market

With high development speed provided by Python, companies can improve time-to-market, which is especially important if you aim to outrun competitors. Reusing the existing code, teams create applications faster while preserving product quality.

When you need to launch the project within tight deadlines, software engineers can employ PyPy just-in-time compiler or move time-essential functions to extension modules built with other programming languages.

2. Nearly 250,000 functionality packages

According to the Python Package Index (PyPI), Python contains about 250,000 packages, allowing engineers to build various software projects and functionality associated with:

  • scientific computing
  • data analytics
  • machine learning
  • system administration
  • graphical user interfaces (GUI)
  • text/image recognition and processing
  • other

What’s more, Python provides web development frameworks such as Flask, Django, Tornado, Zope, Pyramid, and TurboGears that help programmers add various features and create complex business logic with fewer efforts. These frameworks also facilitate the maintenance of complex software solutions.

3. Portability and fast prototyping

Python is a highly extensible coding language with a modular structure, which allows embedding programmable interfaces to existing digital solutions—even those that employ different technologies.

Therefore, software developers can easily fix new modules and connect diverse components, for instance, data analysis, system state monitoring, payment processing, etc. It is worth noting that Python is sometimes named a “glue programming language”. Simple code refactoring is another advantage of Python language.

4. Code readability

Python has a less-structured simpler syntax in comparison with other programming languages. It was designed with code readability in mind. It often employs English keywords instead of punctuation. The formatting of Python coding language is visually uncluttered.

5. Focus on simplicity

Python coding language supports “there should be one—and preferably only one—obvious way to do it” paradigm instead of providing multiple methods to perform a single task.

As a result, there is no need for Python software developers to look for the best way to address a certain issue. The Zen of Python also embraces the following approach: “if the implementation is hard to explain, it's a bad idea”.

What industries employ Python?

As Python allows companies to enable data analytics, complex math calculations, machine learning, image processing, etc. it is employed across all industries: FinTech, InsurTech, banking, retail, e-commerce, business, healthcare, education, science, logistics, manufacturing, social media and entertainment.

Since the Python coding programming language provides enhanced development speed, it is widely used by startups to gain a competitive advantage and pitch their products for investment.

World-famous companies that use Python

Many world-renowned organizations employ Python in their software projects. For example, Reddit, a social networking application with millions of users, is entirely created in the Python programming language.

Examples of famous companies that use Python and industries they belong to:

  • Social networking, image and video sharing platforms—Instagram, Facebook (News - Alert), YouTube, Quora, Reddit.

  • E-commerce—Amazon

  • Cloud storage, client software—Dropbox (News - Alert)
