Suggested small change to code (#5509)

Browse source 
In a code example I think it best to either use full names (index, item) or abbreviated names where that's common (i, item) but not non-standard abbreviations (indx, itm). So I've changed it to index, item since it is a tutorial, although i, item would be just as good.
