Write a NumPy program to create a structured array from given student name, height, class and their data types. Now sort by class, then height if class are equal

import numpy as np
data_type = [('name', 'S15'), ('class', int), ('height', float)]
students_details = [('James', 5, 48.5), ('Nail', 6, 52.5),('Paul', 5, 42.10), ('Pit', 5, 40.11)]
# create a structured array
students = np.array(students_details, dtype=data_type)   
print("Original array:")
print(students)
print("Sort by class, then height if class are equal:")
print(np.sort(students, order=['class', 'height']))
