Exercise 0 (students_test: 1 point). Complete the function get_students which takes a nested list grades as a parameter and returns a new list, students, which holds the names of the students as they from "top to bottom" in the table.
Note: the parameter grades will be similar to the table above in structure, but the data will be different.

Expected Output:

['Thorny', 'Mac', 'Farva', 'Rabbit', 'Ursula', 'Foster']
