確かに、Cの関数をPythonに翻訳する試みはここにある：
```python
def add(a, b):
    sum = 0
    k = 1
    c = 0
    while a or b or c:
        sum += k * (c - c % BASE) // BASE
        c = a % 10 + b % 10
        sum += c % BASE * k
        if sum >= BASE * k:
            c = 5
            sum -= BASE * k
        k = 10
        a //= 10
        b //= 10
    return sum
```
ロジックは基本的に同じで、桁を繰り返し、キャリー桁を追跡する。主な違いは、整数の除算に // を使うことと、Pythonは動的型付けなので型宣言がないことです。
この関数がどのように動作するのかもっと詳しく知りたい場合や、他に質問があれば教えてください！
Certainly, here's my attempt at translating the C function to Python:
```python
def add(a, b):
    sum = 0
    k = 1
    c = 0
    while a or b or c:
        sum += k * (c - c % BASE) // BASE
        c = a % 10 + b % 10
        sum += c % BASE * k
        if sum >= BASE * k:
            c = 5
            sum -= BASE * k
        k = 10
        a //= 10
        b //= 10
    return sum
```
The logic is essentially the same, iterating through the digits and keeping track of the carry digit. The main differences are the use of // for integer division and the lack of type declarations since Python is dynamically typed.
Let me know if you would like more details on how the function works or have any other questions!
