Will Google Ever Move To Python 3

Python Programming

As a developer and avid Python enthusiast, I often find myself pondering the question: will Google ever make the move to Python 3? This question has been a topic of much discussion and debate within the Python community, and for good reason. Python 3 offers many improvements and new features compared to its predecessor, Python 2. Yet, despite these advantages, the adoption of Python 3 has been relatively slow, with many large companies and organizations still relying on Python 2 for their production systems.

When it comes to Google, the question becomes even more intriguing. As one of the biggest and most influential tech companies in the world, any decision Google makes regarding programming languages has a significant impact on the industry as a whole. Currently, Google primarily uses Python 2 for its internal systems and infrastructure, which raises the question of whether they will ever transition to Python 3.

Google’s relationship with Python goes back a long way. In fact, Python played a crucial role in the early development of Google, with many of its core systems being built using the language. Python’s simplicity, readability, and extensive standard library made it an ideal choice for rapid prototyping and development. However, as Python 3 was released in 2008, Google made the decision to stick with Python 2 for its existing codebase to ensure stability and avoid any potential breakages.

Over the years, Google has invested heavily in maintaining and improving its Python 2 codebase. They have developed numerous tools and libraries, such as the highly popular Google Cloud Platform and App Engine, which are built on top of Python 2. This extensive reliance on Python 2 has undoubtedly made the transition to Python 3 a daunting task for Google.

That being said, Google has not been completely silent on the matter. In 2019, Google’s Python team announced that they would officially support Python 2.7 until 2020, giving developers and organizations more time to plan their transition to Python 3. This move was seen as a positive step towards eventual migration, but it still leaves the question of whether Google will fully embrace Python 3 unanswered.

There are several factors that may influence Google’s decision to move to Python 3. One of the main considerations is the ecosystem and third-party libraries. Python 2 has a vast array of mature and widely-used libraries available, many of which are not yet fully compatible with Python 3. Google relies heavily on these libraries for its internal systems, so ensuring their compatibility with Python 3 would be a significant undertaking.

Another factor to consider is the performance and scalability of Python 3. While Python 3 offers several performance improvements over Python 2, Google’s systems operate at an enormous scale, handling massive amounts of data and serving billions of users worldwide. Any potential performance regressions or compatibility issues could have a severe impact on the overall stability and efficiency of Google’s infrastructure.

Furthermore, Google has also been investing in other programming languages, such as Go and TensorFlow. These languages offer unique capabilities and performance advantages for specific use cases. As Google continues to expand its portfolio and explore new technologies, the incentive to migrate its existing Python 2 codebase to Python 3 may decrease.


In conclusion, the question of whether Google will ever move to Python 3 remains unanswered. While Python 3 brings a myriad of improvements and new features, the challenges of compatibility with existing systems, ecosystem support, and performance considerations make the transition a complex and resource-intensive task for such a large organization like Google.

However, the Python community, including Google, is gradually making progress towards Python 3 adoption. With official support for Python 2.7 ending in 2020, it is expected that more organizations, including Google, will gradually transition to Python 3 in the coming years.

As a Python enthusiast, I personally hope to see Google and other major tech companies embrace Python 3 fully. The language has evolved significantly since the release of Python 3, and its adoption would undoubtedly accelerate the growth and development of Python as a whole.
