How to sum the squares of integers from 0 to 5?

Question

Don't understand, please help.

def sum(x):
res = 0
for i in range(x):
res = i*i
res = i*i + i*i
return res
print(sum(6))

doesn't work;(

Answer 1

well, if you want to find the sum then use res+=i*i (res=res+i*i), just change it in your loop

Answer 2

Elias Edgardo Segundo Antonio, great job! Thank you!

Answer 3

you can simplify it.
first, 0*0 is always 0 so it will not affect the sum.
second, use built-in functions and generators.

def squareSum (n):
res = sum(x*x for x in range(1, n+1))
return res
