Nope. Its the other way round. The first axis is the "column" of two rows. Hence length 2. The second axis is the row with 3 elements in each. If you look at it as a table you can access the elements using x,y coordinates. The x coordinate (being first) denotes which row is indicated and the y axis being second denotes the element within the row. > ...But why does the first axis have a length of 2? Because there are two rows. -- 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
