Go vs Python: The Differences in 2024

Python, first released in 1991 by developer Guido van Rossum, has long been the dominant player in the world of programming languages. As a general purpose language designed for simplicity and readability, Python has become immensely popular across fields like data science, web development, system automation, and beyond.

But while Python remains the most widely used programming language today, another contender has emerged that offers key advantages for building fast, scalable systems: Go.

Developed internally at Google in 2009, Go was designed to improve performance for building large networked systems and services. It compiles to standalone machine code that is highly optimized for multi-core and networked computing. While Go adoption started slowly at first, it has absolutely exploded over the past 5 years.

According to Stack Overflow‘s annual developer survey, the percentage of respondents using Go has grown over 5x from just 7% in 2016 to a whopping 37% in 2021. So even though Python remains dominant overall with usage around 60%, Go is rapidly gaining popularity due to its strengths in performance, scalability, and concurrency.

Just how different are Go and Python underneath the surface? Let‘s examine the key distinctions between these two languages as we compare their features, use cases, advantages, and disadvantages for modern software development. Understanding the unique strengths of Go vs Python will provide insight into when to choose one over the other for your next project.

Features of Go and Python

While Go and Python have some surface similarities as open source, garbage-collected languages with simple syntax, they differ greatly in their underlying architectures and capabilities.

Some key differences at a glance:

  • Age: Python is 30 years old; Go is 12 years old
  • Typing: Python is dynamically typed; Go is statically typed
  • Paradigm: Python supports OOP + procedural; Go is procedural
  • Compilation: Python is interpreted; Go is compiled to standalone machine code
  • Concurrency: Python uses GIL; Go has goroutines + channels built-in

Let‘s break down these differences in more detail:


  • Dynamically typed – variable types are checked at runtime
  • Interpreted – code is executed line by line by the Python VM
  • Automatic memory management via reference counting
  • Supports multiple programming paradigms including OOP, procedural, and functional
  • Built-in data types and structures like lists, dicts, sets
  • Large standard library and ecosystem of packages
  • Enforces code readability and simplicity through "the Zen of Python"


  • Statically typed – variable types are checked during compilation
  • Compiles directly to standalone machine code, not bytecode
  • Faster execution with compile-time optimization
  • Supports only procedural programming style
  • Lean standard library focusing on fundamentals
  • Built-in concurrency primitives like goroutines and channels
  • Emphasis on performance, safety, scalability for large systems

So while Python emphasizes developer productivity and simplicity, Go focuses on building robust systems that scale. But which one is better suited for different projects? Let‘s compare their tradeoffs.

Advantages of Python

With 30 years of development behind it, Python offers some compelling advantages:

  • Huge ecosystem – 290,000+ packages on PyPI available for every purpose
  • Beginner friendly – very easy to learn with simple, intuitive syntax
  • Productivity – less code required than lower level languages
  • Libraries – vast array of high-quality Python data science, ML, analytics libs
  • Versatility – great for a wide range of applications and use cases
  • Community – strong support networks and resources for new developers

Python is a great choice when developer experience, rapid prototyping, and ease of use are priorities. The huge ecosystem also provides ready-made solutions so you don‘t have to reinvent the wheel.

Advantages of Go

As a language specifically designed by Google to improve networked systems and cloud infrastructure, Go brings some unique benefits:

  • Performance – compiles to static binary optimized for speed and efficiency
  • Scalability – built-in concurrency model scales well across cores/servers
  • Simplicity – the language specification is small and easy to understand
  • Reliability – strong type safety and testing built into the language
  • Deployment – compiles to single binary with no dependencies
  • Concurrency – lightweight goroutines and channels built right in

Go balances developer productivity with the ability to build high performance systems. It‘s a modern alternative for use cases traditionally associated with C and C++.

Disadvantages of Python

While Python is immensely capable and versatile, it does face some challenges in certain areas:

  • Performance – as an interpreted language, Python is slower for CPU-intensive tasks
  • Scaling – handling 1000s of concurrent requests can require extra work
  • Mobile development – generally not the best choice for writing mobile apps
  • Library maintenance – so many 3rd party libs means more dependencies to manage

If raw speed, efficient scaling, and tight control over resources are critical, Python may not always fit the bill.

Disadvantages of Go

Go is not without its downsides either, especially for newcomers:

  • Learning curve – unique design decisions mean adjusting if you‘re used to OOP
  • Smaller ecosystem – doesn‘t have as many mature 3rd party packages as Python
  • Verboseness – Go code can often be more verbose compared to dynamic languages
  • Lack of generics – can require more boilerplate code compared to generics

While Go was designed to be simple, its procedural style and unique approaches take some getting used to coming from other languages.

Performance Benchmarks

How much of a performance boost does compiled Go code provide compared to interpreted Python? Here are results from some common benchmarks:

  • JSON Encoding: Go is 4.5x faster than Python
  • Web Application: Go req/sec is 7x higher than Python Flask
  • Data Serialization: Go beats Python Pandas by 65x
  • Web Scraping: Go http requests are 2-3x faster than Python

So for tasks like data processing, file I/O, web serving, and scraping – areas where performance matters – Go leaves Python in the dust. The heaviest computations will execute an order of magnitude faster.

But Python has strengths of its own…

Machine Learning and Data Science

For math/statistics-heavy workflows like machine learning, data analysis, and predictive modeling, Python remains the dominant choice thanks to its amazing ecosystem of data tools:

  • Numpy – foundational package for numerical computing
  • Pandas – data manipulation and analysis made easy
  • Matplotlib – powerful 2D plotting and visualization
  • Scikit-Learn – general purpose machine learning library
  • Keras – deep learning and neural network library

These mature Python data science libraries provide everything you need for the full ML workflow. While Go has machine learning packages available, they have yet to match the depth and breadth of Python‘s ecosystem.

So for now, Python remains the primary choice for most data scientists and ML engineers. But Go‘s speed and efficiency can still be highly beneficial for certain ML applications. As the Go ecosystem expands, it will become more capable for complex analytics and ML workflows.

Scalability and Concurrency

One area where Go shines over Python is scalability, or the ability to efficiently utilize multiple CPU cores and servers.

Python‘s default interpreter has a Global Interpreter Lock (GIL) which prevents multiple threads from executing Python bytecodes at once. This makes it harder to take advantage of parallelism across CPUs. Workarounds exist, but concurrency is not Python‘s forte.

Go was designed from the start for concurrent execution. Every Go program runs as a series of lightweight goroutines that can execute independently, synchronized via channels. This model makes it trivial to write asynchronous, non-blocking programs that scale gracefully across many cores and servers.

So for applications like web services, databases, distributed systems – where responsiveness under load is critical – Go‘s baked-in concurrency gives it a clear advantage over traditional Python.

When to Use Python

With its simplicity, vast ecosystem, and versatility, Python excels as a general purpose programming language for many tasks:

  • Building prototypes and MVPs
  • Data analysis, analytics, and machine learning
  • Automation – scripting and task orchestration
  • Backend web development – Django and Flask are popular
  • Scientific computing and numeric processing

If developer productivity is the priority and an existing library already solves your problem, Python is likely the best tool for the job.

When to Use Go

Thanks to its performance and efficiency, Go is purpose-built for large-scale distributed systems:

  • High performance web APIs and microservices
  • Networking apps – distributed systems, cloud infrastructure
  • Highly scalable web and data scraping
  • Databases, caching servers, message queues
  • Command line tools – replacing Bash and Python scripts
  • Cloud-native, containerized applications

For use cases where speed, responsiveness under load, and efficient scaling matter most, Go provides tangible benefits over a dynamic language like Python.

Should You Learn Go or Python in 2024?

I recommend all aspiring developers learn Python first. As one of the easiest languages to get started with, Python will provide a solid foundation in programming concepts that transfers well to other languages.

However, Go is rapidly gaining popularity and brings a modern approach optimized for our cloud-based world. Strong types, built-in concurrency, lightweight execution, and easy deployment make Go an excellent choice as a second language.

Rather than a direct replacement, I see Go and Python as complementary tools in a developer‘s toolkit:

  • Python – for data tasks, automation, prototyping
  • Go – for performance-critical networking and web apps

By mastering both languages, you will be able to select the best tool for the job at hand based on their unique strengths and ecosystem. So devote some time in 2024 to explore Go – it may just become your new favorite!
