>>> import numpy as np
>>> x = np.array([1, 2, 3])
>>> x
array([1, 2, 3])
>>> y = np.arange(10)
>>> y
array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])

>>> a = np.array([1, 2, 3, 6])
>>> b = np.linspace(0, 2, 4)
>>> c
array([ 1.        ,  1.33333333,  1.66666667,  4.        ])
>>> a ** 2
array([ 1,  4,  9, 36])
