It sounds like you want sys.exitfunc, e.g.:

def delete_temp_files():
	os.remove(temp1)
	os.remove(temp2)

import sys
sys.exitfunc = delete_temp_files


or in 2.x do something like:

def delete_temp_files(*tf):
	for f in tf:
		os.remove(f)
import atexit
atexit.register(delete_temp_files, temp1, temp1)
