In general in Python, it is faster and much easier to create a new list rather than to mess about deleting items from a list. So instead of calling del 16 times, which has to move list items around, it will be faster and simpler to create a new list: new = [old[0], old[6], old[13], old[19]] then just use the new list. If you really need to modify the old list in place (perhaps because other parts of the code need to see the same change) then you can do a slice-assignment: old[:] = new # note the [:] slice -- Steven _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
