explain this code:

numbers = [1, 2, 3, 4, 5]
max_index = numbers.index(max(numbers))
print(max_index)
The `max` function returns the largest element in a list of integers and is used to find the index of that maximum value. The line of code `numbers = [1, 2, 3, 4, 5]` creates a variable named "numbers" which contains five elements (i.e., 1 through 5). Then, the statement `max_index = numbers.index(max(numbers))` finds the index of the largest element in the list using the built-in `max()` function. Finally, the line prints the index of the largest element in the list.
