# Python Linked List: Print a given doubly linked list in reverse order

## Python Linked List: Exercise-11 with Solution

Write a Python program to print a given doubly linked list in reverse order.

Sample Solution:

Python Code:

``````class Node(object):
def __init__(self, data=None, next=None, prev=None):
self.data = data
self.next = next
self.prev = prev

def __init__(self):
self.tail = None
self.count = 0

def append_item(self, data):
# Append an item
new_item = Node(data, None, None)
else:
new_item.prev = self.tail
self.tail.next = new_item
self.tail = new_item
self.count += 1

def iter(self):
# Iterate the list
while current:
item_val = current.data
current = current.next
yield item_val

def print_foward(self):
for node in self.iter():
print(node)

def reverse(self):
while current:
temp = current.next
current.next = current.prev
current.prev = temp
current = current.prev
self.tail = temp

items.append_item('PHP')
items.append_item('Python')
items.append_item('C#')
items.append_item('C++')
items.append_item('Java')
items.append_item('SQL')

print("Reverse list ")
items.reverse()
items.print_foward()
```
```

Sample Output:

```Reverse list
SQL
Java
C++
C#
Python
PHP
```
