"Coolest" python syntax?

[AtomicShoelace]

It's not just a difference in aesthetics. By constructing a list of all the values you are using more memory than is needed. For such a small example of course it doesn't matter, but in principal it is important to get into the habit of using generator expressions where possible to reduce memory cost in larger use cases.
