55

Example 2: 1-D Array

import numpy as np

a = np.array([1,2,3,4])

print(a)
[1 2 3 4]

Example 3: 2-D Array

import numpy as np

a = np.array([[1, 2, 3, 4], [5, 6, 7, 8]])

print(a)
[[1 2 3 4]
 [5 6 7 8]]

Example 4: 3-D Array

import numpy as np

a = np.array([[[1, 2, 3, 4], [5, 6, 7, 8]], [[1, 2, 3, 4], [5, 6, 7, 8]]])

print(a)
[[[1 2 3 4]
  [5 6 7 8]]

 [[1 2 3 4]
  [5 6 7 8]]]

Example 5: Higher Dimensional Array

import numpy as np

a = np.array([1, 2, 3, 4], ndmin=6)

print(a)
[[[[[[1 2 3 4]]]]]]
