Hm, I could definitely increase the readability. Maybe I should rewrite it: if _samples_exist(first_sample, last_sample, cpu_core): add samples Why shouldn't I just check if my samples are there if I can? It is much safer than relying on an exception which is delegated through X levels (Yes, just two level here and the method is a helper method just for this context, but still ...) and you don't catch something you didn't want to catch. And in my eyes it is more meaningful.
