  • My programming assignment is not getting scored correctly. I tried to refresh/restart but all the scores are still zero even though all the unit tests are passing
    My lab id is ubxoxewmzytz. Please help

What is the feedback from the grader?
Please post a screen capture image.

I have attached the screen shot for your reference.

Also here is the error: There was a problem compiling the code from your notebook. Details:
‘NoneType’ object is not callable

Thanks for helping out.

Typically this means that somewhere in your notebook, you have left a “None” statement that you need to replace with the correct code.

You cannot grade a partially-complete notebook.

Please check your notebook carefully and report back.
