Issue with continous incrementing of unbroken sequence for a entire working day

Hi,

If you want to have one program running forever and printing sales_records,
you would do (one of the possibilities) something like this:
def salesrecord(serial_number):

    for i in salesrecord:
        print first_sales_record
        serial_number += 1
        print serial_number
    return serial_number

if __name__ == '__main__':
    serial_number = 1

    # Runs this loop until killed
    while True
        <do some stuff: clean serial_number, if day changed, calculate
salesrecord etc.>

        serial_number = salesrecord(serial_number)

If you want to run your script so it finishes and then saves last value of
serial_number, so you can pass it to your script when it runs next time,
you should save the value to some file and read that file on every start of
your program.
