Command not running

Hi, please be kind. I am real beginner and today is my very first class on python. I am following a tutorial, I’m doing exactly as the teacher, but I can’t seem to run any commands. See screenshot:

How can I fix this? Thank you.

Go to Google Colab: https://colab.research.google.com/

Open a new notebook and try to run this code there.
