Generating a Postnet barcode

This script will generate a Postnet barcode (US Postal Service) for a Zipcode that you enter. It uses Tkinter to give you a requestor for the entry. You may enter your numbers and include hyphens if you wish, since these and any other non-numeric characters are ignored.

The barcode is a series of lines drawn to USPS specifications, and in this script is placed vertically (meaning the lines themselves are horizonal), with the beginning of the barcode toward the top of the page at position X = 130, Y = 130 (points).

To relocate the barcode, make the entire barcode a group, so that you can drag it wherever you like or use Properties to place it.
