Why it doesnt work? exercise: Find the sum of all the multiples of 3 or 5 below 1000.

Question

y = []
x = []
a = 0
result = 0
for i in range(1001):
x.append(i)
while a < 1001:
if x[a] % 5 == 0 or x[a] % 3 == 0:
y.append(x[a])
a += 1
a = 0
while a < len(y) or y == len(y):
result = result + y[a]
a += 1

print (result)

Answer 1

this code works, the problem is you include 1000. it says below 1000 so max is 999.

Answer 2

ItzNekS , it's not quiet clear what problem you have, except the ones that Yahya Bey mentioned. What problem do you encounter?

Answer 3

I think your code could be a lot shorter if you only want to calculate result.

Answer 4

thank you. my bad :v
