Hi @Aditya_Kancharla ,

This AssertionError said there are mistakes in your answer.
And also said, perhaps you might be using a global variable defined outside of the function.

In python, we can access global variables from inside a function.
Therefore, we sometimes make a mistake that unintentionally updates the value of a global variable.

Kind regards,
Nakamura
