推荐答案

我认为您正在从Popen对象. html> subprocess 模块.

I think you're looking for the Popen objects from the subprocess module.

请注意，如果您想在该过程之间来回重定向I/O，这种情况将变得很复杂，因为推荐的方法是调用 select 执行I/O的模块.这在Windows上不起作用，因为select()实现仅接受套接字句柄.

Note that if you want to redirect I/O to and from the process, this scenario becomes complex because the recommended way to to this is to call .communicate() which you won't be able to use if you want to manage multiple processes simultaneously. On UNIX-like systems, pipes can be passed to the select() system call so you can use the select module to perform I/O. This won't work on Windows because the select() implementation only accepts socket handles.
