Facing issue with Python loggin logger for printing object value

Hi Dave,
It is able to log the message with:
logger.debug("value of payment_line is " +repr(payment_line))

The output is:
value of payment_line is []

So it means payment_line is an empty list, so may be it could be reason
it's not able to enter into the loop since the message in the for loop is
not logged in the log file.

Thanks and good night.. :)
