Google Colaboratory supports Python version 2.7 and 3.6
I see an example how to use Swift in Colab a while ago.
Today, I happened to run
!jupyter-kernelspec list
And found a new kernel: IRkernel
Available kernels:
ir /usr/local/share/jupyter/kernels/ir
python2 /usr/local/share/jupyter/kernels/python2
python3 /usr/local/share/jupyter/kernels/python3
swift /usr/local/share/jupyter/kernels/swift
Is it now possible to use R in Colab as well? No hassle in installing R kernel?
Yes.
For a new R-notebook, use this link. (shorthand is colab.to/r )
You can learn from IRkernel demos, e.g. demo.ipynb
Save a copy in your Google Drive, and make any changes you need.
