I lost 20 points on the submission due to a “Grading Failed” error. My output matches the sample test case, I’m not sure what is wrong. I got full points on the other questions. Any insight is helpful. Thanks!
Please see this link to learn about grader metadata.
If grader metadata is missing, refresh your workspace and try again.
See Refresh your Lab Workspace section here
If you’ve already done this, contact coursera help
Should you be unsure if this is a metadata issue or your solution is wrong, click my name and message your notebook as an attachment.
The refresh worked thank you!
