Project Euler Problem 1 in Python: Broken iterative solution o(n)

Hey guys, first off I'm a computer science engineer for one of the big companies, and I'm starting a series where I work through coding challenges and try to talk about some optimizations and different tips and tricks to remember as you work through your computer science degrees to land the big tech jobs.

If you want a brief intro about me or any suggestions for the videos. I will answer any questions in the next video I make with your name!

I also figured out why this was messing up at the end. A little too late but we come up with a better solution in part 2 anyways
