Google Colab is an online platform hosted by Google to write, run and share code. Just like a Jupyter notebook environment but hosted entirely in the cloud by Google. Python code can be executed without any setup or installation on your computer.
Its outputs are not limited to text for it can produce very rich interactive visualisations with the many visualisation libraries it supports. Notebooks are easily shared in Google drive and Github. It has links to a bank of shared code and tutorials. With Colab the code are run on Google servers which usually offer better processing power than personal computer.
