The parent-child relationship of processes is where the sub in the subprocess name comes from. When you use subprocess, Python is the parent that creates a new child process. What that new child process is, is up to you. Python subprocess was originally proposed and accepted for Python 2.4...

对于从管道进程和Popen子进程同时读取stdin的需求,可以通过以下步骤实现: 首先,需要导入subprocess模块: 代码语言:python 代码运行次数:0 复制 importsubprocess 接下来,可以使用subprocess.Popen创建一个子进程,并将其与外部命令绑定。在创建子进程时,可以指定stdin参数为subprocess.PIPE,以便从父进程中读取数据: ...
