from subprocess import Popen, PIPE

for line in Popen("find ...", shell=True, stdout=PIPE).stdout:
   # do stuff

or if you don't need shell expansion

for line in Popen(["find", "/some/path", ...], stdout=PIPE).stdout:
    # do stuff

See http://docs.python.org/lib/module-subprocess.html for more.
