Tracking memory usage

[Mark Robinson]

Just wondering. Is there any way to profile the memory usage of my 
program and the data structures in my program in python. I have a 
program that is potentially extremely memory intensive and it would be 
helpful to have this info at the data stucture level of resolution. 
Additionally, I would like to be able to take dynamic alternative action 
if certain data structures exceed certain limits.

I can hope can't I?
