Did you mean to write `students`?

#4

yeah, just experimenting a bit:)

That should be on your time, not ours. When posting a question be sure your code is not experimental. This disrupts other learners. Once you complete a module (all lessons) you are free to go back through it and review and experiment all you wish. But make sure if you post a question about your experiment it is not in the topic forum, but in the Corner Bar.
