Write a Python program to find the size of a singly linked list.

Sample Solution:

Python Code:

class Node:
    def __init__(self, data=None):
        self.data = data
        self.next = None
class singly_linked_list:
    def __init__(self):
        self.tail = None
        self.head = None
        self.count = 0
	
    def append_item(self, data):
        node = Node(data)
        if self.head:
            self.head.next = node
            self.head = node
        else:
            self.tail = node
            self.head = node
        self.count += 1
    
    def iterate_item(self):
        current_item = self.tail
        while current_item:
            val = current_item.data
            current_item = current_item.next
            yield val

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

print("Original list:")
for val in items.iterate_item():
    print(val)

print("nSize of the list:",items.count)

Sample Output:

Original list:
PHP
Python
C#
C++
Java

Size of the list: 5
