Digit fifth powers

Problem 30

Surprisingly there are only three numbers that can be written as the sum of fourth powers of their digits:

1634 = 1⁴ + 6⁴ + 3⁴ + 4⁴
8208 = 8⁴ + 2⁴ + 0⁴ + 8⁴
9474 = 9⁴ + 4⁴ + 7⁴ + 4⁴

As 1 = 1⁴ is not a sum it is not included.

The sum of these numbers is 1634 + 8208 + 9474 = 19316.

Find the sum of all the numbers that can be written as the sum of fifth powers of their digits.

因为9^5 * 6 = 354294 远小于 999999，而9 ^5 * 7 = 413343 < 1000000，因此只要计算到354294即可。

def digitFifthPowers():
    result = 0
    for i in range(2,354295):
        tmp = 0
        for j in str(i):
            tmp += int(j) ** 5
        if tmp == i:
            result += i
    return result

print(digitFifthPowers())
