How to pretty print a numpy array by suppressing the scientific notation (like 1e10)?

# Reset printoptions to default
np.set_printoptions(suppress=False)

# Create the random array
np.random.seed(100)
rand_arr = np.random.random([3,3])/1e3

# output
 array([[  5.434049e-04,   2.783694e-04,   4.245176e-04],
        [  8.447761e-04,   4.718856e-06,   1.215691e-04],
        [  6.707491e-04,   8.258528e-04,   1.367066e-04]])
        
np.set_printoptions(suppress=True, precision=6)  # precision is optional
rand_arr

# output
 array([[ 0.000543,  0.000278,  0.000425],
        [ 0.000845,  0.000005,  0.000122],
        [ 0.000671,  0.000826,  0.000137]])
