That's the First Rule of Optimization, and it's true in any language. 
But in particular in Python or any other interpreted language, if
squeezing a few microseconds here or there is _really_ going to make a
big difference to you, you're probably better off using another language
in the first place.  If processing time is of paramount concern, Python
probably isn't the right choice for the project.
