  For example, to remove the last element of a doubly linked list, one simply does the following: tail = tail.prev tail.next = null size = size-1 Dummy nodes When writing methods (or algorithms in general), one has to consider the "edge cases". For doubly linked lists, the edge cases are the rst and last elements. These cases require special attention since head.prev and tail.next will be null ...

  2014-06-17 · Arrays are similar to lists in Python, except that every element of an array must be of the same type, typically a numeric type like float or int. Arrays make operations with large amounts of numeric data very fast and are generally much more efficient than lists. An array can be created from a list: >>> a = np.array([1, 4, 5, 8], float) >>> a array([ 1., 4., 5., 8.]) >>> type(a)
