Believe it or not, it's the first time I've used a list comprehension for execution like that (other than when working interactively in ipython)! Originally I had a comment about how it was a non-idiomatic thing to do, but I deleted it.

What's strange is that I didn't even consider writing the for loop on a single line. I just never do that. It's clearly better in this case (than a list comprehension). In real code I'd just do it on 2 lines.

I plead guilty your honour, the one-liner syntax for loops is pretty frowned upon among pythonistas too. :-)

It's actually a style violation: https://www.python.org/dev/peps/pep-0008/
