return is only used inside a function, it makes no sense outside (and is a syntax error). Its purpose is to return a value to the caller of the function. Any time you want to get a value back from a function you must use return (or the slightly more esoteric 'yield') Otherwise you will receive the default return value of None. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
