Depends. If you're using a good ol' C-style for loop then nothing's wrong with for(int i = 0; i < something;i++), but if you're doing something like iterating over some collection it's way clearer to do something like for animal in animals: than it is to do for e in animals:. Especially if you're doing something non-trivial for each element
