import queue
 
q = queue.Queue # initialisation

# get() – Remove and return an item from the queue. If queue is empty, wait until an item is available.
# put(item) – Put an item into the queue. If the queue is full, wait until a free slot is available before adding the item.
# empty() – Return True if the queue is empty, False otherwise.  
# maxsize – Number of items allowed in the queue.
# full() – Return True if there are maxsize items in the queue. If the queue was initialized with maxsize=0 (the default), then full() never returns True.
# get_nowait() – Return an item if one is immediately available, else raise QueueEmpty.
# put_nowait(item) – Put an item into the queue without blocking. If no free slot is immediately available, raise QueueFull.
# qsize() – Return the number of items in the queue.

queue python

Comment

from queue import Queue  # watch out with the capital letters

# Making the queue
queuename = Queue()

# We use .put() to insert value and .get() to pop the first one.
# You can think this as a normal queue

queuename.put(1)  # adds int 1 to index 0
# To access the queue, you need to change it to list
print(list(queuename.queue))
# Output : [1]

queuename.put(2)  # adds int 2 to index 1
print(list(queuename.queue))
# Output: [1,2]

queuename.get()  # removes index 0 (int 1)
print(list(queuename.queue))
# Output: [2]

# We can simulate the same effects using normal list, but the longer the queue
# the more ineffecient it becomes

queuesimulate.append(1)
print(queuesimulate)
# Output : [1]

queuesimulate.append(2)
print(queuesimulate)
# Output: [1,2]

queuesimulate.pop(0)  # 0 is the index number
print(queuesimulate)
# Output: [2]

# Python program to

from queue import Queue
  
# Initializing a queue
q = Queue(maxsize = 3)
  
# qsize() give the maxsize 
# of the Queue 
print(q.qsize()) 
  
# Adding of element to queue
q.put('a')
q.put('b')
q.put('c')
  
# Return Boolean for Full 
# Queue 
print("\nFull: ", q.full()) 
  
# Removing element from queue
print("\nElements dequeued from the queue")
print(q.get())
print(q.get())
print(q.get())
  
# Return Boolean for Empty 
# Queue 
print("\nEmpty: ", q.empty())
  
q.put(1)
print("\nEmpty: ", q.empty()) 
print("Full: ", q.full())
  
# This would result into Infinite 
# Loop as the Queue is empty. 
# print(q.get())
