If it will be a floating point value then you need to use float(). In your example I'd have thought it reasonable to allow conversions of, say, 11.5 inches... I meant to add that its generally considered good practice to do the conversion as early as possible unless you plan on using the string version later. So wrapping the input() call inside the int or float call is good. You can then wrap that inside a try/except and get the user to re-try if they type invalid data - if you so wish... -- 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
