Google Colaboratory, or “Colab” for short, is a product from Google Research. Colab allows anybody to write and execute arbitrary python code through the browser and is especially well suited to machine learning, data analysis, and education. More technically, Colab is a hosted Jupyter notebook service that requires no setup to use while providing access free of charge to computing resources, including GPUs.
By default, it starts the runtime with Python version 3.7. If you want to upgrade the version in your current notebook, then follow these steps in the given order:
1) !python --version
Python 3.7.13
2) !sudo apt-get update -y
