Multi-Dimensional Arrays

A multidimensional array is an array that includes other arrays as its elements, forming a matrix or a higher-dimensional structure.

We can create 2D, 3D, and 4D arrays using the following format:

python
Copy code

For example, we can create a 2x2 matrix using the following code:

We can also initialize it with some data using the following syntax:

We can access and modify the elements of a multidimensional array using indexing by specifying both the row and column's index of the element:

Following is an illustration of a 2D array with 9 elements:

An array can have as many dimensions as needed. Following is an example of a 5-dimensional array:

The above array will have 240 elements based on the calculation 2 x 3 x 4 x 5 x 2 = 240. The following code shows the declaration and initialization of a 3D array called `numbers:
