Is there a reason to put spaces in between calculations? for example 2+2 vs 2 + 2, because the output is the same.
Besides that is there any rule for leaving a space?
No, it's just a matter of personal preference. I personally like to leave a space between operators so it's easier to read and distinguish them from each other. Other than that, there is no difference.
Fran pep8 has something to say about that...
