Might also be worth adding logging INFO comments. E.g. replace the calls to print with calls to logger_name.info. And, as I think is your intent with this issue, we'd configured the logging output to go to both the terminal and also into a log file written to disk, the latter being a good tool for forensics on crashes of the system when it is running unattended, amongst other things.
