You're partially right - what I want is a function that is free of side effects back through the parameters passed in the function call. Side effects via globals or print statements is fine by me. 

python seems to be undergoing changes all the time. List comprehensions were added in python 2.0, according to wikipedia. I like list comprehensions and use them all the time because they are powerful and concise.
