Jupyter does not execute code in Ubuntu 16.04

Question

I'm running Ubunutu 16.04 with Python 3.6 and I have installed Jupyter notebook, now whenever I try to run jupyter notebook notebook it opens up in a browser but without any button to run the code, and outputs the code as plain text.

What should I do to fix this?

Answer 1

Jupyter is made to run and edit noteboks (.ipynb files), not .py files.
