list can be used as a simple queue in Python.
q =  for i in range( 0, 5 ): q.append( i ) # Add to back of queue while q: # Queue not empty j = q.pop( 0 ) # Get from front of queue print( j ) # Output: 0 1 2 3 4
Note that popping the first item of a list is not optimal due to the way it is implemented. For large queues, using deque as queue is a much better option.
