what built-in python data type is commonly used to represent a queue code example

Example: queues in python

class Queue:
    def __init__(self, capacity):
        self.front = self.size = 0
        self.rear = capacity - 1
        self.Q = [None] * capacity
        self.capacity = capacity

    def isFull(self):
        return self.size == self.capacity

    def isEmpty(self):
        return self.size == 0

    def EnQueue(self, item):
        if self.isFull():
            print("Full")
            return

        self.rear = (self.rear + 1) % (self.capacity)
        self.Q[self.rear] = item
        self.size = self.size + 1
        print("%s enqueue to queue" %str(item))

    def DeQueue(self):
        if self.isEmpty():
            return "Empty"

        print("%s dequeued from queue" %str(self.Q[self.front]))
        self.front = (self.front + 1) % (self.capacity)
        self.size = self.size - 1

    def que_front(self):
        if self.isEmpty():
            print("The Queue is empty")


        print("Front item is ", self.Q[self.front])

    def que_rear(self):
        if self.isEmpty():
            print("Queue is Empty")

        print("The rear item is ", self.Q[self.rear])


queue = Queue(30)
queue.EnQueue(10)

queue.que_front()
print()
