什么是计算argmax的pythonic方法？

Question

如果我有一个列表和一个计算得分的函数,我可以这样计算argmax:

maxscore = 0; argmax = None
x = [3.49, 0.122, 293, 0.98] # Imagine a LARGE list.
for i in x:
    # Maybe there're some other func() to calculate score
    # For now just sum the digits in i.
    score = sum([int(j) for j in str(i) if j.isdigit()])
    print i, score
    if maxscore < score:
        maxscore = score
        argmax = i

有没有其他方法来实现argmax？什么是pythonic方式呢？

Answer 1

def score(i):
    return sum([int(j) for j in str(i) if j.isdigit()])

max(x, key=score)
