1,进程间通信 Process有时是需要通信的,操作系统提供了很多机制来实现进程之间的通信,而Queue就是其中的一个方法 ---这是操作系统开辟的一个空间,可以让各个子进程把信息放到Queue中,也可以把自己需要的信息取走 ---这就相当于系统给python开辟了一个聊天室,让python创建的子进程可以在这个聊天室里畅所欲言 ---...
以下例子利用Python内置的queue模块构建了一个队列,将0-9按顺序依次放入队列中。然后,检查队列是否为空,如果不为空,则将队列中的数据一个一个取出并打印输出: 代码语言:javascript 复制 # author:测试蔡坨坨 # datetime:2024/4/144:02#function:FIFO先进先出队列 ...
I'm using multiprocessing in my project. I have a worker function which put in a queue the results. Everything works fine. But as size of x increases (in my case x is an array) something gone wrong. Here is a simplified version of my code: def do_work(queue, x): result = heavy...
The best solution I can come up for this is utilising a queue, so each message function is queued behind the next. However I get issues with it being in a thread. Here's the start of my working class: class RpiLCDMenu(BaseMenu): def __init__(self, pin_rs=26, pi...
