How do I execute multiple shell commands with a single python subprocess call?
Question: 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.


Answer: 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.
