my answer was:

Python

N=eval(input("enter a number:"))
s=0

    if i%3==0 and i%5==0 :

Solution 1

First, you don't have to specify an else if there's nothing to do outside of the conditions you've been given.

Next, the program spec says

Quote:
Write a function giving the sum of the integers of [1,N] divisible by 3 or 5.

You might want to look a little closer at your code to see if your code matches that condition.

First, you have to fix your ifcondition. As suggested, look again at the requirement. See if your code complies.
The else part is optional, if you don't need it, then omit it.
