How to change jupyter kernel from Python 2 to python 3?

I have installed Jupiter notebook and I only have python 2 as a default kernel. I want to change it from python 2 to python 3. How could I do that?Here is the screenshot.


Follow the link for managing python. If you use python 2, then install python 3 by using this command.

conda create -n py36 python=3.6 anaconda

After installing python 3, activate python 3 by using this command

activate py36 

Then open jupyter notebook, you will find python on your kernel.
