Python 3 support in Google's CoLab

Question

I have been experimenting with the Jupyter notebooks at https://colab.research.google.com, and it seems that by default they run Python 2.7.

Is there any way to enable Python 3 support on CoLab?

Answer 1

Yes! Python3 support is now live in Colab.

• When creating a new notebook, there's now an option for Python2 or Python3.

• For an existing notebook, Runtime -> Change runtime type will let you switch.

We write the language info into the kernelspec in the notebook metadata, so switching runtime type isn't just per-session.
