Why to Change Python Version in Google Colab?

Let’s explore some scenarios where downgrading Python can be quite handy:

1. Library Compatibility: Sometimes, certain Python libraries and packages aren’t updated to work seamlessly with the latest Python versions. If your project heavily depends on such libraries, downgrading Python can be the smart solution to ensure everything plays nicely together.

For instance, picture yourself working on a machine learning project within Colab. You’re using an older machine-learning library that hasn’t caught up with Python 3.10 (the default version in Colab). To make sure your project runs smoothly, you’ll want to downgrade to Python 3.8, the version your library is cozy with.

2. Legacy Code: Another common scenario is when you’re dealing with legacy projects or code that was written in an older Python version. In such cases, downgrading Python is like dusting off the old books – it ensures that your code hums along without hiccups.

Imagine you’re the guardian of a legacy web application built with Python 2.7. You need to make some updates or squash a few bugs. Colab prefers Python 3.8 and onwards, so you’ll gracefully step back to Python 2.7 for this nostalgia-filled coding journey.

3. Project Requirements: Collaboration is a beautiful thing, but it can sometimes come with specific Python version requirements. These requirements can be project-specific or set by the competitions you’re participating in.

Let’s say you’re in the midst of a data science competition on Kaggle, and the rulebook states that submissions must be made using Python 3.6. To make sure your submissions are A-OK, you’ll adjust your Colab environment to Python 3.6.

4. Personal Preference: Lastly, it’s not all about compatibility and rules. Personal preference plays a role too. Some data scientists and developers have their own comfort zones when it comes to Python versions, often tied to their familiarity or past experiences.

You, as a data whiz, might have a soft spot for Python 3.6. The syntax, the behavior – it just feels like home. While Colab generously offers you newer Python versions, you might opt for a cozy Python 3.6 environment for your personal coding pleasure.

Thankfully, downgrading Python in Google Colab is a breeze. Stick around, and we’ll walk you through the simple steps.

Google Colab is an incredibly versatile platform for data science and machine learning. It offers a virtual environment equipped with a variety of pre-installed software tools, and the best part is, that it’s free! In this guide, we’ll take you through the process of downgrading the Python version in Google Colab.

Typically, Google Colab comes bundled with the latest Python version, which is generally a good thing. However, there are situations where you might need an older Python version due to compatibility issues with specific libraries or project requirements. Here, we will change and downgrade Python version.
