Queue.Queueandcollections.dequeserve different purposes. Queue.Queue is intended for allowing different threads to communicate using queued messages/data, whereascollections.dequeis simply intended as a datastructure. That's whyQueue.Queuehas methods likeput_nowait(),get_nowait(), andjoin(), whereas...

Deque as Stack Data Structure TheStackclass of theJava Collections frameworkprovides the implementation of the stack. However, it is recommended to useDequeas a stack instead ofthe Stack class. It is because methods ofStackare synchronized.

Also, as a historical note, this structure appeared first in Hoogerwoord's A symmetric set of efficient list operations in 1992. I learned this fact in Exercise 5.1 of Okasaki's Purely Functional Data Structure. → Reply k1r1t0 16 months ago, # ^ | +16 doesn't rebalance make it ...
由此可见,deque是在另一个模块_collections中实现的。我们在Lib中并没有找到_collections模块,它很有可能是一个用C语言实现的模块。我们回到Modules目录看一看,果然找到了Modules/_collectionsmodule.c。 这个源码文件就是deque实现之所在,不难找到deque对象底层结构体定义(71~96行): ...
