Just a personal note. I dislike while True loops which depend on break statements to control the flow of execution because it makes the loop harder to trace and understand.

Just a note that doing so much array concatenation is expensive rather than concatenating to the same area each time.

Just a note that queue.pop(0) is an O(n) operation. Python does have a deque data structure which provides a similar O(1) operation.
