I guess i better stop posting these long spaghetti code things, but this
is the first pass at a menu based general decision analysis thing...it
has four parts, one is general any question, two is programming language
choosier expert system , tow is scripting language chooser, four is a
basketball predictor expert sysstem...does anyone know of any Python
expert system type of programs I could look at are??? I am interested in
any artificial intelligence Python programs or Expert System Python
programs...


anyway...this program runs fine under Python Win but fails under IDLE
for unknown reasons..."Tcl error expected boolean got??" after I give it
the first answer to the first prompt...
