In this example, the first index value is 0 for both index arrays, and thus the first value of the resultant array is y[0, 0]. The next value is y[2, 1], and the last is y[4, 2]. If the index arrays do not have the same shape, there is an attempt to broadcast them to the same shape. If they cannot be broadcast to the same shape, an exception is ...

In this case, we assign the new_value (4) to the element at the specified index (2) using the list assignment my_list[index] = new_value. Finally, we print the updated list, which now has the value 4 at index 2. However, if the condition index < len(my_list) is False, it means that the index is out of range for the
