Well, theres exec() and eval() built in functions (i think) ... but if 
you want to continually feed in statements and stuff, you might want to 
look at the interpeter-builing tools in the code module. 

There are also some issues about sandboxing and restricted execution of 
untrusted code, some of which may be a part of these modules, but I 
don't know much about that and if you are doing this for debugging or 
simulation and you aren't worried about picking up a string from 
somewhere along the lines of "import os;os.system("deltree /y c:\*")" 
and killing some end-user's box... you probably don't need to worry 
about that stuff.
