Data science and machine learning

Python is one of the most commonly used languages within the machine learning and data science communities. According to the 2018 Octoverse report, Python is the number one choice for machine learning. As of 2018, PyTorch ― a Python library for machine learning ― was one of the fastest-growing projects on GitHub, while TensorFlow ― a Python open-source platform for machine learning ― was among the projects most contributed to.

Developers choose Python for these new fields because of its simplicity, flexibility, stability, and great community. If you have any difficulties developing your project, there are plenty of Python forums and groups, so you’re sure to find answers to your questions.

One more reason why developers go with Python for machine learning and data science is the wide range of scientific libraries the language has. For example, you can use TensorFlow, Keras, and scikit for machine learning; NumPy, Pandas, Seaborn, and SciPy for data analysis and visualisation; and NLTK and spaCy for natural language processing.

Web development

Python is the top choice for web development. The reasons for this are many: ease of use, readability, robustness, maintainability, versatility, flexibility, and security. Also, there are a wide range of web frameworks Python offers to simplify development. Among the most popular are Django, Flask, Tornado, Pyramid, web2py, Bottle, and CherryPy. Django and Flask took the tenth and eleventh spots in the list of most commonly used web frameworks by Stack Overflow in 2020.

The fact that Python is widely used for data science, machine learning, and web development proves that the language won’t disappear soon. These fields, especially data analysis and machine learning, aren’t going away anytime soon.

Python in action: Companies that use Python

Another way of looking at Python market demand is by considering real-world Python projects. According to BuiltWith, there are 246,163 websites that use Python as of February 2021. Among world-famous companies that use this language are Instagram, Google, Netflix, Reddit, IBM, Facebook, Spotify, Quora, and Dropbox. Let’s take a moment to review some of them. 

Reddit

Python hasn’t been an essential part of Reddit from the start. Originally, Reddit was written in Common Lisp, but six months later the company migrated to Python. During the Python Conference in 2009, Reddit CEO Steve Huffman commented on the company’s shift to Python, saying there were two major reasons for it. The first was that Python had more libraries. The second was it's writable, expressive, and readable code.

Reddit hosts over 330 million monthly active users, has over 21 billion screen views each month, contains more than 130,000 active communities, and is the fifth most visited website in the US. To handle high loads and ensure efficient and fast performance, Reddit uses Python.

Netflix

One of the world’s leading entertainment media service providers, Netflix has been using Python as the main technology from the beginning. They use Python across all of their processes, combining in-house software libraries with well-known Python packages.

Where exactly does Netflix use Python?

  • To build and operate Open Connect, a content delivery network (CDN) delivering Netflix movies and TV shows to subscribers across the globe

  • To create in-house tools for capacity operations, regional failovers, traffic distribution, and fleet efficiency of the Netflix cloud for the Demand Engineering team

  • Statistical analytics and alerting

  • Automation tasks, visualization, and data exploration and cleaning

  • Monitoring, diagnostics, alerting, and auto-remediation inside the Insight Engineering team

  • Security automation, vulnerability identification, and risk classification

In addition to the use cases mentioned above, Netflix relies on Python for machine learning. The algorithms they apply include:

  • Recommendation algorithms to understand exactly what their users are in the mood for.

  • Artwork personalization algorithms – Since user preferences differ, Netflix realized it’s better to find the best image for each user by pointing out the aspects of a title that are directly related to the user’s interests.

  • Marketing algorithms to save time on marketing – With algorithms, Netflix has automated their paid marketing campaigns.

We’ve asked our Python developers: What’s the future of Python?

It’s clear that Python is on the rise. But what about its future? We’ve asked our Pythonistas about what to expect from Python in the future. Here’s what they said.

I’m sure that Python and its incredible ecosystem will continue to grow in the future. And using this language will be an indispensable skill needed for software engineers of any branch.

- Bogdan Primakovski,
Data scientist & machine learning engineer

The future of Python is promising. Up to now, Python has been in demand in areas such as web development, software development, and system administration. With the rise of data science and Python scientific packages such as NumPy, pandas, and Matplotlib, Python popularity is growing.

- Kate Zublenko,
Senior Python developer

I suppose that Python will continue to assert itself among asynchronous languages. Not only asyncio, a powerful and productive solution built in Python’s standard library, but also the fact that Django, one of the most popular web frameworks, will support asynchronous syntax out of the box attests to this.

- Volodymyr Manushko,
Technical leader

Python is a very popular programming language designed more than 25 years ago. Python can be used in different areas starting from web development to desktop app development to machine learning to big data to data analysis to robotics. There are many reasons why people like this language and why it’s well suited for different projects, including clean syntax, very understandable code, a wide range of uses, packages that help implement features, and a cool community that helps develop this great language. To answer the question regarding Python’s future, I’d say that I’m pretty sure this language has a great future.

- Stanislav Rybonka,
Python developer

Python is a mature and full-fledged programming language that had for a long time been conservative. Yet recently, Guido van Rossum, the creator of Python, has stepped down from his role of Benevolent Dictator for Life (BDFL). This means that we’re supposed to expect new features from new Python leaders.

But apart from the Python standard library, there are a bunch of external libraries that shape Python development and are no less important. This is where everything is good: new frameworks and libraries are created and old ones are improved. Data science is one of the new fields that is actively being developed. And Python is a superstar there.
