`import numpy as np` load Numpy module for Python	`np.array` declare Numpy array
`[[1, 2], [3, 4]]` sample array data	`np.square` calculates squares for each value in a given array
`arr` array to calculate squares for values of

import numpy as np
arr = np.array([[1, 2], [3, 4]])
arr = np.square(arr)
print(arr)

[[ 1  4]
