IndexError: index 4 is out of bounds for dimension 1 with size 3

This error message indicates that you are trying to access an element in an array or list using an index that is outside the range of valid indices for that array or list. In this case, the array or list has a size of 3 in the second dimension, but you are trying to access an element at index 4, which is out of bounds.

For example, if you have an array like this:

my_array = [[1,2,3],[4,5,6],[7,8,9]]

And you try to access an element using an out-of-bounds index like this:

print(my_array[1][4])

You will get the IndexError message:

IndexError: index 4 is out of bounds for dimension 1 with size 3

To fix this error, make sure that you are using valid indices when accessing elements in your arrays or lists.
