I just completed a nice example of integrating IBM i system commands with Python when you have a need to update your system time. The IBM i has a built in time sync, but in my case some of the firewalling services I used get in the way so I needed a way to update on demand via an NTP time server. And Python didn't disappoint.
Check out this link for the Python code example:
