input: Write a python function to create a structure combining student and teacher attributes.
  assert createStructure([0.5, 0.6], [0.8, 0.9]) == [0.5, 0.6, 0.8, 0.9]
  assert createStructure([0.1, 0.2, 0.3], [0.4, 0.5, 0.6]) == [0.1, 0.2, 0.3, 0.4, 0.5, 0.6]
  assert createStructure([0.0, 0.1], [0.2, 0.3, 0.4]) == [0.0, 0.1, 0.2, 0.3, 0.4]
output: def createStructure(student_attributes, teacher_attributes):
      return student_attributes + teacher_attributes
