In python, how can i get the multiplication of array elements using recursion?

I want to get the multiplication of array elements using recursion.

arr is array, and n is length of the array.

if arr=[1, 2, 3], n=3, answer is 6.

I tried this, but error occurred.

def multiply(arr, n):
    if n == 0:
        return arr
    else:
        return arr[n] * \
               multyply(arr[n - 1])

please help me.

>Solution :

You should implement it like this

def mul(arr):
    if not arr:
        return 1
    return arr[0] * mul(arr[1:])
