Why this code doesn’t work as expected?
I know there are other ways to reverse list using recursion
but I am interested particularly in why this method doesn’t work.

def reverse(nums):
    if len(nums) < 2:
        return
    nums[0], nums[-1] = nums[-1], nums[0]
    reverse(nums[1:-1])


A = [1, 2, 3, 4, 5, 6]
reverse(A)
print(A)

I am expecting the output [6 5 4 3 2 1].
