input: Write a python function to create a list of Student objects with names and grades and retrieve their names and grades.
  assert students[0].get_name() == 'Alice' and students[0].get_grade() == 90
  assert students[1].get_name() == 'Bob' and students[1].get_grade() == 85
  assert students[2].get_name() == 'Charlie' and students[2].get_grade() == 95
output: class Student:
