UnableToFindJupiterNoteBook

I am new to DeepLearning.AI
Prompt engineering was my first course…
And I am not a working professional just a student who would be joining CSE at NIT Calicut… [I know basics of Python from 11th/12th and using spyder for working]

Can someone please explain in easy steps where we need to code?
and can I continue using Spyder for this ?

Also, how do we find the key ?

For anyone wondering about this:
This is not a course with a credential, there are no assignments, so you do not need to code anywhere. The key used in the course is stored in the backend and cannot be accessed by you. If you want to have your own key you can get this here.
