ValueError: list.remove(x): x not in list

Describe your environment

I work on Exercise 1 and I meet a problem.

Describe your question

image image From my perspective, i is in the list1 and obviously it it in the student_list, but there is error.

Describe the efforts you have spent on this issue

I have Google it but I do not find some similar problem.

you can print list1 and student_list before the error line. Then you can verify whether x is in or not
