Part10-12_course_records gives error in 'test_1_add_works_1'

[farwashah6]

My code is checked and verified by the server and everything is fine. Also, I have not put the main under if name == "main" block!, but in the end it is showing me this error
Your program does not output anything.
Check that it is not inside if name == "main" block!

Please help, or let me know if the checker is looking for a certain name of class, because it is not mentioned in the exercise problem.

Thank you
