well, you can use

 >>> s = '123456'
 >>> [int(s[i:i+2]) for i in range(0, len(s), 2)]
[12, 34, 56]
 >>> f(*_)
102

While your "f()" is just a boring placeholder I assume, you could 
also write that as

  sum(int(s[i:i+2]) for i in range(0, len(s), 2))

and skip creating f() altogether if all it does is add its arguments.
