Numpy: Sort an array

# Import library
import numpy as np

# Create an array
x = np.array([[5,2,0],
             [1,7,6],
             [3,9,4]])

print(x)

[[5 2 0]
 [1 7 6]
 [3 9 4]]

# Sort
y = x.copy()
y.sort()

print('Sorted array (default)(axis=1):\n',y)
print(type(y))
print('Size:',np.size(y))

Sorted array (default)(axis=1):
 [[0 2 5]
 [1 6 7]
 [3 4 9]]
<class 'numpy.ndarray'>
Size: 9

# Sort
y = x.copy()
y.sort(axis=0)

print('Sorted array (axis=0):\n',y)
print(type(y))
print('Size:',np.size(y))

Sorted array (axis=0):
 [[1 2 0]
 [3 7 4]
 [5 9 6]]
<class 'numpy.ndarray'>
Size: 9
