    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.
