An easy way to think about the stack data structure is through the undo list in a text editor. Typing in an editor adds a new action to a stack. When you then choose the “undo” action, the last item added to that stack gets removed from the stack. The action that item represents...

一、迭代器 迭代(iteration) 迭代是数据处理的基石,扫描内存中放不下的数据时,我们需要找到一种惰性获取数据项的方式,即按需一次获取一个数据项,迭代器对象从集合的第一个元素开始访问,直到所有的元素被访问完结束。迭代器只能往前不会后退,这就是迭代器模式。 迭代
Queue.put_nowait(item) 同put(item, block=False) Queue.get(block=True, timeout=None) 从队列中移除并返回一个项目。 如果可选参数 block 为 True:(1)timeout 为 None (默认值) 时,会在必要时阻塞,直到项目可得到;(2)timeout 为正数时,将阻塞最多 timeout 秒,如果在这段时间内项目始终不能得到,...
