Can ytou simplify the problem momentaruily? Can you create a list of dates then search that list for a range of dates? That is forget about the csv file issues and focus on the date problem? That might make it easier to see where you are having the issues. > have an if elif statement to read row5 which is the date row.

That obviously cannot be a range you need a start and end point. And then you need to see if the target date lies between those two points. And for that you need a way to compare them. Comparing dates as a general problem is very, very difficult. Fortunately the datetime module and the timedelta object within it simplifies things for your use case. -- 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
