In this Python Programming video tutorial you will learn about doubly Linked List data structure and also you will write the program for traversing operation in detail. • Data structure is a way of storing and organising the data so that it can be accessed effectively. • Linked List is a linear data structure made up of chain of nodes in which each node contains a data field and link or reference. • There are different types of linked list. Here we will discuss about 3 common types of linked list. doubly linked list is one of them. Here we will discuss doubly linked list operations and definitions in detail. • Here we will write two methods for traversing operation, one is for forward traversing and another for backward traversing. • Forward Traversing: • def print_LL(self): • if self.head is None: • print( Linked List is empty! ) • else: • n = self.head • while n is not None: • print(n.data) • n = n.nref • Backward Traversing: • def print_LL_reverse(self): • print() • if self.head is None: • print( Linked List is empty! ) • else: • n = self.head • while n.nref is not None: • n = n.nref • while n is not None: • print(n.data) • n = n.pref • • #DataStructures #PythonPrograms #LinkedList • For more free tutorials on computer programming • / amulsacademy • twitter.com/AmulsAcademy
