The short answer is Memory. Doubles take up twice as much memory as Integers. Here is one of Stack Overflow's threads on the subject for further reference.
Keep Coding!

Also consider data types and appropriate typing - If you know you wont be using fractional values (think of a record ID in a database or the score of a ping pong match) it would be semantically correct to use an Int over a Double in your logic. Keeping track of and using appropriate types helps keep your code clean and easier to debug.

Python Web Development Techdegree Student 38,322 PointsIn this project it's really up to you if you want to use int or double, but I believe Jeremy McLain says something about int being easier for the computer to work with, and if in a big project you use double instead of int then it could result in a lower performance - not 100% sure though.
