Queues in PYTHON

 The Python Code for Queue is here :-

class Node: def __init__(self, data): self.data = data self.next = None class Queue: def __init__(self): self.front = self.rear = None def enqueue(self, data): newnode = Node(data) newnode.next = self.rear self.rear = newnode if self.front is None: self.front = newnode def dequeue(self): temp = self.rear while temp.next is not self.front: temp = temp.next self.front = temp temp.next = None def traverse(self): temp = self.rear while temp is not None: print(temp.data, end = " --> ") temp = temp.next print("None") new = Queue() new.enqueue(4) new.enqueue(1) new.enqueue(0) new.enqueue(2) new.traverse() new.dequeue() new.traverse() new.dequeue() new.traverse()
2 --> 0 --> 1 --> 4 --> None 2 --> 0 --> 1 --> None 2 --> 0 --> None

So this was the Python code for Queues. Hope you understood the code. Please share it with your friends and help them learning python.
