## Code Before:
c = get_config()
c.CourseDirectory.db_assignments = [dict(name="1", duedate="2019-12-09 17:00:00 UTC")]

]
c.ClearSolutions.code_stub = {'python': '##### Implement this part of the code #####\nraise NotImplementedError()'}

## Instruction:
Add error message for not implemented error
## Code After:
c = get_config()
c.CourseDirectory.db_assignments = [dict(name="1", duedate="2019-12-09 17:00:00 UTC")]
c.CourseDirectory.db_students = [
