You build a wrapper module that does just this for you. See 
Python->Mac->Lib->findertools.py for an example of this for the 
finder. This gives a syntax which is similar to Applescript, i.e.

in applescript you have

Tell application "finder" to sleep

in Python its


A word of caution. Python only allocates/can use one transaction 
number per session. So if your script calls do_script more than once 
it will fail. So far I have only found this to be a problem scripting
