Neither do we because we don't know what you are talking about. There is no context. How does a user select these items? Is it a web page? a GUI? A CLI? An in-store sensor that detects items being removed from the fridge? (Maybe under the control of a Raspbery Pi or Arduino?) And how do you know the original prices? Are they hard coded? read from a data file or database? Input by the user? Or maybe the fridge sensor reads bar codes attached to the actual items? How do you calculate the total? Is it stored in a variable? Is it stored as a floating point value (you should never do that for money!) or as an integer number of pennies/cents? If the latter total -= 100 Is the obvious answer to your question. Is it even in code or do you just write it down on paper? Or maybe you are using an electronic calculator? I could go on but hopefully you see how little information you have given us to work from.? If it is in code show us what you hae so far and we can help you add this feature. Without any clue what you are doing we can't really help very much. -- 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
