该API与 multiprocessing.Process 类非常相似,可能与 subprocess.Popen 类更相似。具体来说,它与 subprocess.Popen 共享 wait()、communicate() 和 send_signal() 等方法以及 stdin、stdout 和 stderr 等属性。 现在我们知道了 asyncio.subprocess.Process 类是什么,让我们看看如何在我们的 asyncio 程序中使用它。 我...

You run a shell command using subprocess by calling subprocess.run() with the command as a list of arguments. subprocess.call(), subprocess.run(), and subprocess.Popen() differ in how they execute commands and handle process output and return codes. multiprocessing is for parallel execution wit...

Subprocess - subprocess.Popen wrapper with timeouts, polling and almost the same API, as SSHClient (except specific flags, like cwd for subprocess and get_tty for ssh). async_api.Subprocess - the same, as Subprocess helper, but works with asyncio. .. note:: for Windows ProactorEventLoop or...
