Go vs. Python – which one is better for machine learning?

Python is the most popular machine learning language, but the less popular, like Go, also have supporters. Read our comparison of Python and Go in ML.

Python is the most popular language for machine learning, but does it mean it is the best? Today there are more and more followers of less popular languages, such as, for example, Go. If you are wondering which one to choose – this article is for you! Here is a comprehensive comparison of these two languages that will allow you to make the right decision!

"Go is a programming language with growing popularity. According to HackerEarth’s survey, Go ranks first among the languages students and experienced programmers would like to learn.

The growing interest in this language in the fields of AI and data science results mainly from its speed and the naturally occurring multithreading. These two features make Go a competitor of the most frequently used artificial intelligence programming language – Python, which sometimes causes problems in these aspects."

Overall popularity 

Today Python is the fastest-growing programming language. According to the results of Stack Overflow Developer Survey, it is the third most popular technology used by software developers. 

Moreover, it is also the second most loved programming language among IT specialists.


According to Stack Overflow, the average annual salary of a Python developer is $63k. Which puts it on the 12th place on the list of the top-paying technologies.

Why is Python used for machine learning?

Machine learning requires continuous data processing, and Python is perfect for working with large datasets. Furthermore, due to the huge amount of analyzed data in ML, it’s necessary to create solutions that will be both effective and simple. For this purpose, Python is the perfect solution because its structure is easier to use than other programming languages.

Moreover, the syntax of Python is really simple. Many people who want to become a machine learning engineer and do not yet know any programming language start their learning with Python. And it is an excellent choice!

One of the essential reasons why Python is good for ML is a vast library ecosystem. It has a lot of useful machine learning libraries such as:

  • TensorFlow - is one of the best libraries for working with ML on Python. It is a scalable, flexible, and fast open-source solution used for research and production.
  • Keras - is an open-source neural network library that extends the usability of TensorFlow with additional features for ML and DL programming. Engineers use it for effective and fast datasets processing.
  • Scikit-Learn - easy use and flexible library focussed on data modeling. It allows for easy integration with different ML programming libraries.

These are just a few of the huge collection of available Python libraries for Machine Learning.

Lastly, it is important to highlight that Python is also flexible, which enables choosing the programming styles. We can even combine a few of them to solve various types of problems in the most effective way. 

Pros and cons of using Python for machine learning


  • a low barrier to entry
  • universality
  • popularity and large community
  • a huge number of frameworks and machine learning libraries
  • highly rated machine-learning repositories


  • speed limitations
  • weak in mobile computing
  • underdeveloped database access layers
  • a very few statistical model packages


Go (also known as "Golang") is a comparatively new programming language, launched in 2009 by Google. Its syntax is similar to C, so individual developers say that it is the C for the twenty-first century. Despite lacking the popularity of Python, Go has a lot of followers who see its great potential.

  • relatively few libraries (especially ML libraries)

Python vs. Go – which one is better for machine learning?

We already know the pros and cons of Python and Go. So, it's time to answer the critical question – which programming language is better for machine learning? 

Let's start with the common features. Both languages have simple syntax and are easy to learn for beginners. Both are also very flexible, and they can be used in almost any project. 

And finally, both have far more advantages than disadvantages. 

And what about the differences? First of all, Python is older and more popular. The greatest competitive advantage of this language is the very extensive range of various useful machine learning libraries. However, it is also significantly slower and more prone to bugs than Go. 

Go is not as popular as Python, but it has a lot of followers who see its great potential. It is growing fast, so it may be a serious competition for Python in the future. Today we have to admit that Go is faster, more scalable, and performant so that it is perfect for large-scale projects. And that makes it one of the best choices to work on machine learning infrastructure


In conclusion, if you want to develop ML-based solutions, knowing and using Python is a requirement. It is currently still one of the best choices to develop machine learning algorithms. However, if you want to actually run a production machine learning API at a bigger scale, you need professional infrastructure. And in this case, Go is probably a better solution.
