Calculate the sum of all digits of the base to the specified powerΒΆ

Calculate the sum of all digits of the base to the specified power.
Test Data:
If power_base_sum(2, 100)
Expected output:
115
def power_base_sum(base, power):
    # str() to make 'int' object iterable
    return sum([int(i) for i in str(pow(base, power))])

# test
print(power_base_sum(2, 100))
print(power_base_sum(8, 10))

Output:

115
37
