Python Study, queue, stack, priority queue, example source code

import queue

def GetItemList(q):
    ret = []
    n = q.qsize()
    while n>0:
        n -= 1
    return ret

l = 'apple,banana,orange'

#queue test
q = queue.Queue()
for x in l.split(','):

print( GetItemList(q) )

#stack case
#LIFO last in first out
q = queue.LifoQueue()
for x in l.split(','):
print( GetItemList(q) )

q = queue.PriorityQueue()
print( GetItemList(q) )

out put is...
['apple', 'banana', 'orange']
['orange', 'banana', 'apple']
[(1, 'orange'), (5, 'apple'), (10, 'banana')]
