[Zope] How to check memory usage in Python

Hi, This is more a Python question. How can one check the RAM memory usage of a Python program from within itself? Is there such a function? (Is it platform independent? I mean, does such a function exist for most platforms?) If such a function does not exist in Python, how can one do it from Unix (or Windows) shell calls? thanks, Hung Jung ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
