Some examples: a[start:end] # items start through end-1 a[start:] # items start through the rest of the array a[:end] # items from the beginning through end-1 a[:] # a copy of the whole array a[-1] # last item in the array a[-2:] # last two items in the array a[:-2] # everything except the last two items HTH, -larry -- https://mail.python.org/mailman/listinfo/python-list
