There were several good solution programs for [[CSC111 Homework 6 Solution 2014| Homework 6]].  You were not required to use a '''main()''' function, although some did.  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.
