[Tutor] Crossword program

Wed Jan 12 14:43:55 CET 2005

Thanks Alan for that suggestion.  I will try and tidy it up myself and then ask the tutor list for another suggestions.

Its probably the kind of thing you could put on the
Useless Python website. Useless is a collection of
not-too-serious software written in Python which,
despite the name, is actually quite useful for beginners
to download and look at and learn. They can try
improving it, or using the ideas for their own
programs.

But you might well get some suggestions on tidying
it up a little first...
