Queue 操作都是原子操作. 队列里面支持两种数据结构: FIFO (先进先出) 和 LIFO (后进先出). Queue 支持多线程操作. 使用Queue 需要导包: from multiprocessing import Queue q = Queue() q.put(100) print(q.get()) print(q.empty()) print(q.full()) #### 管道(Pipe): pipe 方便实现进程通信. pipe 的原理就是两端连接起来了就像管道那样互相发送数据. pipe 只能连接两端 (单向通信) pipe 实际上就相当与 socket 操作. pipe 不支持多线程操作. 使用pipe 需要导包: from multiprocessing import Pipe parent_conn , child_conn = Pipe() parent_conn.send(100) print(child_conn.recv()) #### 管道(Pipe): queue.Queue 具备以下功能: * 支持多线程操作 * 内置锁机制保证多线程安全 * 支持FIFO 和 LIFO 数据结构 * 内置了非常多实用功能 (比如 full empty 判断) * 不支持跨平台通信 (windows 不支持) Pipe 具备以下功能: * 不支持多线程操作 * 不支持FIFO 和 LIFO 数据结构(只能单纯连接两端进行通信) * 不支持 full empty 判断 (无法判断是否满/空) * 支持跨平台通信 (windows linux 都支持)<|repo_name|>chenyuec/cpp-learn<|file_sep scope 表示范围 scope 给变量设限制 python 中变量无需声明. python 中变量属于动态语言. python 中变量属于弱类型. python 中变量属于动态绑定. python 中变量属于强引用计数.
