Sorting Arrays

Now, let's dive into sorting arrays. Sorting an array involves arranging its elements in a specific order, whether it's ascending, descending, or some other sequence.

Let's try to sort the array:


              
123456

            
import numpy as np

array = np.array([3, -4, 6, 0, 12, 499, -123])

print('unsorted array', array)
print('sorted array', np.sort(array))
copy

Note

The sort() function returns a copy of the array, while the original array remains unchanged.

Let's try to sort a 2-D array:


              
12345

            
import numpy as np

array = np.array([[-2, 4, -12, -434, 62], [1, 4, 7, 93, 75]])
print('Unsorted array', array)
print('Sorted array', np.sort(array))
copy
Task
