Hello @Sandeep_Sharma1,

I suggest two things:

  1. Make sure your assignment notebook is in its original format (please don’t put the codes together). The autograder relies on the right format to work properly. If you need, you may follow these instructions to refresh your notebook, and then you can copy your work back.

  2. After you make sure the format is correct, run the code again, and share a screenshot of the Error Traceback, if any.

not defined bug isn’t difficult to solve, and it only requires some careful inspection, but we need to see the Error Traceback first.

Cheers,
Raymond

PS: Sharing assignment work is in violation of the community’s guideline, so I am removing it for you.
