An operating system doesn’t boot up with thousands of processes, though. Many of the processes you’re familiar with are started by you. In the next section, you’ll look into the lifetime of a process.Process Lifetime Think of how you might start a Python application from the command ...
RuntimeError: Queue objects should only be shared between processes through inheritance. 进程与线程对比 定义的不同 进程是系统进行资源分配和调度的一个独立单位. 线程是进程的一个实体,是CPU调度和分派的基本单位,它是比进程更小的能独立运行的基本单位.线程自己基本上不拥有系统资源,只拥有一点在运行中必不可...
