Several of the exercises produce the expected results but are scored 0. I’ve rebooted from the help menu and tried again. Any suggestions? Thanks
I’m not a mentor for that course.
But in general, passing the tests in the notebook does not guarantee your code is perfect. The grader always uses a different set of test cases.
What is the detailed feedback from the grader? Please post a screen capture image.
I checked a couple of the assignments. Two had incorrect column names. After fixing, the tests passed.
