NameError: name 'book_title' is not defined
Tip: Every time you open a notebook, you have to run all of the cells starting from the top.
That’s where the assets are imported and the workspace is configured.
Perhaps this will help.

Sorry, but I’m not a mentor for that course, so I can’t answer specific questions about the grader’s tests.
no worries, thanks anyway. How do i find my mentor?
You’ll need to wait for a mentor for that course to reply here.
@community-team, can you help with this?
Thanks a ton. i will wait.
Hi. Did you use an f-string for all the four? Initially, it said book_title was not defined and then it changed to f-strings.
This means you need four print statements with f-strings. Each of your print statement should have something like f”{title}”. It says you have 3 instead of 4. Check for the f-string you missed. I had that problem while I was checking out the exercise.
Just that I do not have access to the notebooks at the moment as I am not a mentor for the course.
Thank you, i added 5th f string and it solved the problem, somehow it was not recognizing 4th f string so i added 5th f string and it worked.
