| + | The program below is a good example of how Python programs should be organized, with a header first, possibly a few import statements, maybe a constant or two, then a long list of function definitons ('''def''' statements), then the definition of the '''main()''' function, and at the very end, one call to '''main()''' that starts the whole program. | ||
