Well, if you go by the disassembly, Python does put the condition at
the top of the loop. But I've seen plenty of C compilers that invert
that - before the top of the loop it jumps down to the bottom, the
bottom has the condition, and the condition may or may not jump you up
to the top of the loop.

Semantics :)
