如果它们是独立的，请使用分号链接它们.

例如(Python 3)

>>>导入子流程>>>result = subprocess.run('echo Hello ; echo World', shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)>>>结果CompletedProcess(args='echo Hello ; echo World', returncode=0, stdout=b'Hello\nWorld\n')

但从技术上讲，这不是纯 Python 解决方案，因为 shell=True.arg 处理实际上是由 shell 完成的.(您可以将其视为执行 /bin/sh -c "$your_arguments")

如果你想要一个更纯粹的解决方案，你必须使用 shell=False 并循环你的几个命令.据我所知，没有办法直接用子进程模块启动多个子进程.

Ideally it should be like a list of commands that I want to execute and execute all of them using a single subprocess call. I was able to do something similar by storing all the commands as a shell script and calling that script using subprocess, but I want a pure python solution.I will be executing the commands with shell=True and yes I understand the risks.

Use semicolon to chain them if they're independent.

For example, (Python 3)

>>> import subprocess
>>> result = subprocess.run('echo Hello ; echo World', shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
>>> result
CompletedProcess(args='echo Hello ; echo World', returncode=0, stdout=b'Hello\nWorld\n')

But technically that's not a pure Python solution, because of shell=True. The arg processing is actually done by shell. (You may think of it as of executing /bin/sh -c "$your_arguments")

If you want a somewhat more pure solution, you'll have to use shell=False and loop over your several commands. As far as I know, there is no way to start multiple subprocesses directly with subprocess module.
