Adding Digits in Python (or Smarter-looking doesn't mean better)
- chriswitts 11y agoSurprised you didn't have `sum(map(int, number_string))` in there. In [5]: def f(x): ...: x = str(x) ...: return sum(map(int, x)) In [6]: %timeit second_way_optimized(x) 1000 loops, best of 3: 200 µs per loop In [7]: %timeit f(x) 1000 loops, best of 3: 223 µs per loop Marginally slower, a hell of a lot easier to read what's going on.
