How do I execute multiple shell commands with a single python subprocess call?
<p>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. </p>

<p>Use semicolon to chain them if they're independent.</p>

<p>For example, (Python 3)</p>

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

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

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