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)
