Description: I submitted the week 2 practice lab assignment many times, but the grader is continuously giving 0 grade. There is a problem in auto- grading system, the deadline of the assignment is May 11. I checked my assignment many times, it show all tests passed, but grade is still 0.

This is extremely unlikely, given that the course is years old and has not been updated recently.

Passing the tests in the notebook does not prove your code is perfect. The grader uses different tests.

So, please review the code you added to the assignment, and verify that you have implemented the code correctly.

Pay particular attention to what variable names you re using inside the graded functions. Avoid using global variables.

Do not make any changes outside of the marked areas marked for you to add your code.

Do not add cells, move cells, or delete cells, and only modify a cell specifically where instructed.

I tried many times and I also followed these rules, but there is a problem in auto-grading system. My all tests passed,but grade 0.

I just ran my code through the grader, and it got a score of 100%.

So I recommend you check your code again.

Or, perhaps delete your notebook and use the Lab Help “Get latest version” tool to get a new copy, and start over.

Also: Have you perhaps renamed a copy of your notebook?

The grader cannot use a file that you have renamed. it will always use the notebook with the original file name.

You can delete your notebook by using the “File → Open” menu, then select the checkbox by the notebook name, and a red “trash can” icon will appear in the menu. Click on that.

Then use “Get latest version”, then exit the assignment page and reload it.
