C5W4 A1 Transformer (Can't compile the student's code.)

Hi mentors,

When I submit my code for the assignment, I get 0 with the error message, “Cell #18. Can’t compile the student’s code. Error: AssertionError(‘Wrong values case 1’)”

the code runs fine passing all the tests but I’m not sure where it went wrong.

Would you be able to give me some help?

I renamed my file which was the issue to be graded.
Thank you!
