And your point is?
100 invocations of a subordinate shell and 100 initializations and
invocations of Python will take time, no matter what 'cmd' is or how
fast Python executes it.
Just a note that if you want to do something efficiently in a do shell
script command, do as much as possible in one do shell script
invocation (that is, write a shell script and execute it in toto with
do shell script), rather than invoking do shell script repeatedly.
This also allows you to retain state (such as working directory,
environment variables, etc.) between shell commands.
AppleScript commands are modeless and stateless, so there's always a
cost to executing them repeatedly.
