[Python-Dev] python optimization

I use cpython. I'm accustomed (from c++/gcc) to a style of coding that is
highly readable, making the assumption that the compiler will do good
things to optimize the code despite the style in which it's written. For
example, I assume constants are removed from loops. In general, an entity
is defined as close to the point of usage as possible.
I don't know to what extent these kind of optimizations are available to
cpython. For example, are constant calculations removed from loops? How
about functions? Is there a significant cost to putting a function def
inside a loop rather than outside?
