As to length I expect both languages to end in the same ball park. Here's a 
possible Python implementation:

from itertools import zip_longest

def prepare(s):
    return map(int, reversed(s.split(",")))

def naive_add(base, left, right):
    result = []
    carry = 0
    for a, b in zip_longest(prepare(left), prepare(right), fillvalue=0):
        carry, rest = divmod(a + b + carry, base)
        result.append(rest)
    if carry:
        result.append(carry)
    return ",".join(map(str, reversed(result)))

if __name__ == "__main__":
    print(naive_add(16, "1,2", "13,14"))

The Python code for sure has better indentation ;)
