Problem 6: Sum square difference

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

1² + 2² + ... + 10² = 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.

Find the difference between the sum of the squares of the first one hundred natural numbers and the square of the sum.

这第六题python实现最简单吧

max1 = 100
 
sum1 = 0
sum2 = 0
for i in range(1,max1+1):
    sum1 += i**2
 
sum2 = ((1+max1)*max1/2)**2
print(sum2-sum1)
