在Python中,可以使用subprocess模块来运行具有实时输出的子进程。下面是一个示例代码: 代码语言:txt 复制 import subprocess def run_subprocess_with_realtime_output(command): process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.STDOUT, shell=True) while True: output = process....
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...

child.stdout child.stderr 我们可以在Popen()建立子进程的时候改变标准输入、标准输出和标准错误,并可以利用subprocess.PIPE将多个子进程的输入和输出连接在一起,构成管道(pipe): import subprocess child1 = subprocess.Popen(["ls","-l"], stdout=subprocess.PIPE) ...
