ProjectEuler#56 Powerful digit sum

#A googol (10**100) is a massive number: one followed by one-hundred zeros; 100**100 is almost unimaginably large: #one followed by two-hundred zeros. Despite their size, the sum of the digits in each number is only 1.

#Considering natural numbers of the form, a**b, where a, b < 100, what is the maximum digital sum?

max = 0
for i in range(100):
    for j in range(100):
        number = str(i**j)
        acc = 0
        for k in number:
            acc += int(k)
            if acc > max:
                max = acc
print max
