I am getting zero grade, need help to find the root cause

For all exercises, I got this error “Grader found global variables inside graded fuctions. Please avoid using global variables in your functions.”

I verified all of my functions, even I refreshed the environment, with new notebook did all my changes again. Still getting the same error.

I could not debug where I am using global variable. Can you please help?

My lab id is tbjjugja

Hi Shankar_Raju,

I hope this issue was resolved. If not, I can report this to someone working at the backend.
