Addition and Product of a List Python

Question::

Define a function sum() and a function multiply() that sums and multiplies (respectively) all the numbers in a list of numbers. For example, sum([1, 2, 3, 4]) should return 10, and multiply([1, 2, 3, 4]) should return 24.

Code::

def add(l):

    s=0

    for j in l:

        s=s+int(j)

    return s

def multiply(l):

    m=1

    for j in l:

        m=m*int(j)

    return m

d=input("Enter List: ")

n=d.split(",")

print("Entered List=",n)

print("Addition is:",add(n))

print("Product is:",multiply(n))

Output::
