Quick answer: No.

Long answer:
In *nix, there are various programs that tell you the amount of memory a 
resident process is using, my personal favorite for process information 
is ps.  You may be able to query it with the proper string to find the 
total amount of memory Python is using in total, which may or may not be 
useful.  There are utilities for windows that functionally mirror *nix 
ps.  Either could be run from within Python, to be processed with python 
via:
a = os.popen('ps <args...>', 'r')
output = a.read()
a.close()
