Project Euler: Problem 6

https://projecteuler.net/problem=6

The sum of the squares of the first ten natural numbers is,

$$1^2 + 2^2 + ... + 10^2 = 385$$

The square of the sum of the first ten natural numbers is,

$$(1 + 2 + ... + 10)^2 = 552 = 3025$$

Hence the difference between the sum of the squares of the first ten natural numbers and the square of the sum is 3025 − 385 = 2640.

one_hundred = [i for i in range(1,101)]
square_hundred = [i**2 for i in range(1, 101)]

sum_square = sum(one_hundred)
square_sum = sum(square_hundred)

print(sum_square**2)
print(square_sum)

diff = (sum_square**2) - square_sum
