Week 1 Assignment ( 0/100 grade)

I can’t find out the Error statement in program.

feedback: Cell #6. Can’t compile the student’s code. Error: TypeError("‘NoneType’ object is not iterable")

That error usually means you have left some “None” values in the functions.

Did you complete the entire notebook before you submitted it for grading? You can’t submit a partially-complete notebook.

Appreciate for you responding me! I re-named the first file, and I complited in a v2 vision, and submit when I finished all cells in v2 file. Should I delete other files?

The file you submit for grading must have the original file name.
You can’t submit a notebook file that has a different name.
The grader always tests the notebook file that has the default name.
