Ideally, you should be using python’s “logging” library to write to a file if you don’t want it going to the journal. But if you must make systemd handle it, use StandardOutput=file:/path/to/logfile. Make sure your service has access to that file to write.
You can’t use shell redirects in Exec lines since systemd units aren’t shell scripts. You can, of course have the service include:
Exec=/use/bin/bash -c “pythonscript > /var/log/script.log”
