Python: Creating multidimensional arrays with unspecified dimensions

Python ellipsis (...) Data Type: Exercise-6 with Solution

Write a Python program that uses 'Ellipsis' to create a multidimensional array with unspecified dimensions.

Sample Solution:

Code:

import numpy as np
# Create a multidimensional array with unspecified dimensions
nums = np.array([[[1, 2], [3, 4]], [..., ...], [[5, 6], [7, 8]]])
# Print the array
print(nums)

Output:

[[list([1, 2]) list([3, 4])]
 [Ellipsis Ellipsis]
 [list([5, 6]) list([7, 8])]]

In the exercise above, we use 'ellipsis (...)' to represent unspecified dimensions in a NumPy array. The resulting array contains 'ellipsis' as placeholders for dimensions not explicitly specified. In this way, we can create multidimensional arrays without having to specify all dimensions in advance.
