Dear all,
after my submission of the assignment, the grader said always with error message “name ‘Stack’ is not defined”. However, the class Stack has been defined by default and has been never changed. Important is all tests were passed and there was no error message by executing the notebook, but except the grader.
Can someone help it?
Thank you!
I am guessing you might have changed something in the class stack. If I was you I would feed the code from class stack and stackfixed to the LLM along with the error and see what advice it gives you first!
If you think you might have altered something you can always reset the lab at the question mark in the right hand corner in the “Get Latest Version”
Thank you for the reply!
Actually it was the encoding and format issue in the editor. I have fixed it by copy text in local and recopy back.
