python list as queue code example

Example 1: queue python

from queue import Queue

q = Queue()

q.size() # returns the current lenght of queue
q.empty() # returns True if empty, False otherwise
q.put(item) 
q.get()

Example 2: python list as queue

# Demonstrate queue implementation using list
 
# Initializing a queue
queue = []
 
# Adding elements to the queue
queue.append('a')
queue.append('b')
print(queue)
 
# Removing elements from the queue
print("\nElements dequeued from queue")
print(queue.pop(0))
print(queue.pop(0))
 
print("\nQueue after removing elements")
print(queue)
 
# print(queue.pop(0)) will raise and IndexError as the queue is now empty

Example 3: queue in python

#creating a queue using list

#defining a list

my_queue =[]

#inserting the items in the queue

my_queue.append(1)

my_queue.append(2)

my_queue.append(3)

my_queue.append(4)

my_queue.append(5)

print("The items in queue:")

print(my_queue)

#removing items from queue

print(my_queue.pop(0))

print(my_queue.pop(0))

print(my_queue.pop(0))

print(my_queue.pop(0))

#printing the queue after removing the elements

print("The items in queue:")

print(my_queue)
